Greetings! I'll be doing another hardcore Python course this summer in the San Francisco area. If you're somewhat new to Python or have tinkered but want to fill-in the holes, this course is for you. It's somewhat true you can learn Python online, watching videos, or reading books, but it still takes time and experience to master... I help accelerate this process. The course is based on my bestselling "Core Python" books and is made up of 3 full days complete with lectures and three hands-on coding labs per day.

Greetings! I'll be offering another hardcore Python course this summer near the San Francisco airport. If you're somewhat new to or have some Python experience under your belt already but want to fill-in the holes, this course is for you. Why take a real course when you can learn Python online or by reading books? Well, my goal isn't to teach Python syntax, which you can from any teacher, live or online, or from giant books. My job is to create great Python developers and removing the roadblocks that impede your path to getting there. This intensive course is based on my "Core Python" (http://corepython.com) books and is made up of 3 full days complete with lectures and several hands-on coding labs per day. t's also a great excuse to coming to beautiful Northern California for a summer vacation! Groups and development teams are welcome as well as individuals. I do more private gigs and fewer of these public courses lately, so please come join if you can... my next public intro/intermediate course may not be for awhile, so I'm hoping to meet some of you this time around! Sign up soon... there's a special earlybird rate for the rest of this month before going up to the regular rate after that. More details and registration at http://cyberwebconsulting.com as well as in the ad: http://goo.gl/pyJseQ I'm no fan of spam, so I'll only send out one last reminder as the date gets closer... say around the end of June.

"Core Python" target audience is comprised of those who know how to program in any other high-level language, i.e., C/C++, Java, Perl, Tcl/Tk, PHP, etc., who want to learn Python as quickly and as comprehensively as possible, then be introduced to a variety of specialized topics with which to continue to develop your Python skills with. it is not the bible, as that would be the docs that already come with Python. i'd say it's about 40% beginner, 40% intermediate/advanced, and 20% reference. if you're looking for a pure reference, check out Beazley's PER or Martelli's Nutshell. if you're absolutely new to programming, check out Dawson's Absolute Beginner or Downey/Eklner's How to Think like a Computer Scientist. if you want a large case study (tons of examples, i.e., everything *plus* the kitchen sink), look for Lutz' massive Programming Python. if you only know shell scripting, you should still be able to pick up much of the material in Core Python, esp. if you have done looping and/or conditionals in the shell language. it is a large book and is pretty comprehensive though, so if you're looking for a lighter intro, the books gene's suggested should work -- i would also add Dive into Python to that group. if possible, try to find sample chapters from any book you're interested in before buying to make sure that it will suit your needs. when you start delving into Python, come over to the Python Tutor mailing list. if you have a question that no book seems to be able to answer or seems to be taking forever to look up, you'll find that you can get just about any answer from the helpful tutors on that list. yiassoo! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list

(double feature) > From: "Ray" <[EMAIL PROTECTED]> > Date: Tues, Aug 1 2006 2:10 am > > Hi Wesley, which edition of Python will your latest Core Python cover? > Will it cover 2.5? ray: thanks for asking. one of my goals for the book is to really cover the *core* parts of the language, meaning that, like Python, i try to keep it version independent. if you write an app using 2.3, it should pretty much run unmodified in 2.4, etc. in other words, regardless of which Python release you use, the book will have relevant material. it is not too often that something about the core part of the language changes enough to make a significant impact on the applications that people write. with that said, i can tell you that the book has been updated to 2.5, as well as includes some features already set for 2.6 and 2.7, and also presumably 3.0. in the book, we've placed markers or logos that *tag* when an important feature was added to Python, so if you're still using 2.4 say, you can skip over stuff from newer versions, or at least read about them so that you know what's possible if you migrate. so far, the book has been pretty well received after speaking with some (OSCON) conference attendees who saw the rough draft last week at the convention bookstore. hope this helps! -wesley > From: John Salerno <[EMAIL PROTECTED]> > Date: Tues, Aug 1 2006 6:48 am > > wesley chun wrote: >> if you want a large case study (tons of >> examples, i.e., everything *plus* the kitchen sink), look for Lutz' >> massive Programming Python. > > which is also coming out in a new edition soon. i believe that mark's book will be released around the same time as Aahz' Python for Dummies (another possible first book for newbies), and Core Python will come around several weeks later -- i know is that we are hitting the printers sometime this week, followed by the binding, distribution, shipping, etc. once the publisher or amazon has some sample text, i'll be glad to share it with you. there is a sample chapter from the 1st ed at the book's website (link below) if you want to get a taste of my writing style -- that hasn't changed between editions. ;-) cheers, -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list
Re: How do I put % in a format sting?
as fredrik and others have mentioned, '%%' in a format string gives you the single '%' in the string as desired. however, in your specific application (database), it's best to avoid using Python's string formatting unless that is the default provided by your database adapter for the reasons that carsten mentioned, namely the possibility of a SQL injection attack. when dealing with databases, it's always safest to let the adapter code format your string for you. good luck! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list
Re: building strings from variables
> Following a discussion with an associate at work about various ways to build strings from variables in python, I'd like to hear your opinions and preferred methods. from the performance standpoint, i believe that #4 (list join) from scott is the fastest. #1 (string formatting) is next preferred only because #3 (string concat) is the worst [think "realloc()"]. #2 is useful for when you have users who aren't as comfortable with #1. however, #3 is good for real newbies or those coming from other languages since conceptually, it's the easiest to comprehend. bottom line is that it depends on your requirements. i'm constantly thinking performance, so that's why i answered in the manner above. hope this helps! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list

welcome to Python!! i too, have (recently) been interested in COM
programming, so much so that i added some material on Microsoft Office
(Win32 COM Client) Programming to the 2nd ed of my book, "Core Python
Programming" (see link below). it's only introductory material, but i
think you may find it useful as i have, and shows you how to create
simple applications for Excel, Word, PowerPoint, and Outlook.
in addition to greg's code snippet, here's a snippet based on one from
the book (the code is under a CC license) -- it doesn't add a new
sheet, but does let you grab the "active" one (the one that is tabbed
and facing the user):
# based on excel.pyw in Core Python Programming, 2nd ed
from time import sleep
import win32com.client as win32
def excel():
xl = win32.gencache.EnsureDispatch('Excel.Application')
ss = xl.Workbooks.Add() # add a new spreadsheet/workbook
sh = ss.ActiveSheet # grab the active sheet of the workbook
xl.Visible = True# make Excel show up on the desktop
sleep(1)
sh.Cells(1,1).Value = 'Python-to-Excel Demo'
sleep(1)
for i in range(3, 8):
sh.Cells(i,1).Value = 'Line %d' % i
sleep(1)
sh.Cells(i+2,1).Value = "Th-th-th-that's all folks!"
sleep(5)
ss.Close(False) # close the workbook and don't save
xl.Application.Quit() # quit Excel
if __name__=='__main__':
excel()
hope this helps!

fabian,
see below for a PP example. you mentioned you were coming from a
linux OOo system... are you trying to do COM stuff with OOo? i'm not
familiar with it, but since they do support
some level of VB-like scripting, i don't believe it's out of the question.
one thing that i did forget to mention in my earlier message is that i
use static dispatch for these apps. if you did not go and run the
makepy utility, you would have to use dynamic dispatch, start your
apps with win32com.client.Dispatch(), or, using the same import
statement as below, win32.Dispatch().
anyway, here is pretty much the same script as i sent earlier but for
PowerPoint instead of Excel (the book has small examples for each of
Excel, Word, PowerPoint, and Outlook):
# based on ppoint.pyw in Core Python Programming, 2nd ed
from time import sleep
import win32com.client as win32
def ppoint():
ppoint = win32.gencache.EnsureDispatch('PowerPoint.Application')
pres = ppoint.Presentations.Add()
ppoint.Visible = True
s1 = pres.Slides.Add(1, win32.constants.ppLayoutText)
sleep(1)
s1a = s1.Shapes[0].TextFrame.TextRange
s1a.Text = 'Python-to-PowerPoint Demo'
sleep(1)
s1b = s1.Shapes[1].TextFrame.TextRange
for i in range(3, 8):
s1b.InsertAfter("Line %d\r\n" % i)
sleep(1)
s1b.InsertAfter("\r\nTh-th-th-that's all folks!")
sleep(5)
pres.Close()
ppoint.Quit()
if __name__=='__main__':
ppoint()
HTH!

Re: Observation on "Core Python Programming"
(warning: LONG reply) thanks to those above for the kind remarks. tackling comments and questions, not quite in chronological order. :-) > Who would you say the book is aimed at? Advanced programmers? this book is targeted towards technical professionals already literate in another high-level language who wants to pick up Python as quickly as possible. it is not a topical coverage of a programming language's features. you know how after learning a new language, it takes a few months to really "feel comfortable" enough to *not* pick up a book in order to commence writing code? my goal is to reduce that time period while provide the reader a comprehensive understanding of how the standard types work, esp. in their relationship to Python's memory model. it is my belief that a solid foundation here will reduce or eliminate any potential bugs you would've written had you read a more conventional introductory text. > What really jumped out at me is an interesting feature about how > it sequences its topics, namely, (user-defined) functions are not > introduced until chapter 11, fully 400 pages into the book. i guess i found this post quite interesting because there is such a focus on "what should be introduced when." the purpose of chapter 2 (getting started) is to proxy for the standard "introduction to programming X" book. if you read it, you should be able to "get started in Python" immediately. you have enough info on functions to start coding and probably don't need var args, decorators, or any of that stuff yet. the chapter on functions occur later because most of the time, what we've shown you in "getting started" is enough to, ummm..., get you started, and that all successive chapters are meant to dive more deeply into each area. > seems to confirm the "batteries are included" philosophy of > Python. Perhaps there is less need to learn how to roll your > own batteries as soon as possible. this is definitely one of the hallmarks of the language. the current user base already knows this... it's just more difficult to get this out there to the general programming populus, esp. when there are already so many languages starting with "P". :-) > The revenge of lambdas. Will they stay or will they go?" ;-) they will stay. ;-) > am interested in seeing the extend to which Python is genuinely > "multi-paradigm" - able to blend the functional and imperative > (and OO) paradigms together. this comes from guido himself. he "wants you to be able to see the forest through the trees." i see Python as a "greatest hits" of many computer programming languages. for our benefit, he's given us the best stuff. > I cant' exactly figure out why yet, but he has a way of explaining > something, like, say, decorators, that in minimal words elucidates > for me the intent behind why they are useful. That helps me > understand how they work. "Python fits your brain." (bruce eckel) i don't see why python should have a monopoly on your brain. i want me share too. ;-) the thing that makes writing a pleasurable is when the language has so much to offer. i use this book in teaching my python courses, and the book mirrors my lecturing style. i suppose that rather than a dry college textbook, i'd rather write in a way as if i was having a conversation with you, or if you were actually sitting there attending one of my courses. readers (as well as course attendees) have remarked how questions they may come up with as they are learning a topic are answered in the next section or chapter (or 3-4 presentation slides) as the case may be. > The second edition site doesn't give a sample chapter (but > does give the complete preface) ahhh, the secret here is that you need to look in the right place. "prentice hall"s web page doesn't have it, but PHPTR's does, even if they are the same publishing house. for some reason, we've got the featured book of the month!! just go to http://phptr.com and click the book's link there. you'll find: - book's description - table of contents - preface - sample chapter (getting started, chapter 2!) - index the last three are in PDF format. if for some reason, october ends and it's gone from the front page, here is a direct link: http://phptr.com/title/0132269937 thanks to everyone for their support, esp. my excellent technical reviewers for keeping me honest! please send comments, suggestions, corrections, and other feedback to me. i am happy to hear about any issues you find in the book -- everything. it doesn't matter if it is the smallest grammatical edit, errors in the code, or just plain wrong or misleading information. don't believe everything you read! (sometimes writing at 2, 3, and 4a in the morning does something to your writing when you're trying to tackle a publisher's deadlines.) keep checking the book's errata page at http://corepython.com all book correspondence should go to corepython at yahoo dot com. cheers! -- wesley - - - - - - - - - - - - - - - -

Re: does anybody earn a living programming in python?
since 1997, i've been pretty much working full-time in Python: - at yahoo, we developed yahoo!mail in python (and some C++) - at synarc, i wrote software for doctors in python (and some C) - at ironport, most everything is in python (and some C, PyRex). we have a million lines in python (http://www.python.org/about/quotes/) for the forseeable future, i plan on keeping it this way. i took a contract which led me back to C, but as i was doing this, most of the time i felt like i was "wasting my time," e.g., char **x = (char**)malloc(...)... *x++ = (char*)malloc(...) ... free()... free()... (segmentation fault)... bus error... gdb... blah blah, led to thoughts such as, "i have better things to do with my time," "when does this contract end?", etc. it did, however, make me more appreciative of the C code which comprises the Python interpreter. i sense that because i had done that (C) before and realized how Python makes me more efficient, that i've become "spoiled" by it and am more picky about my opportunities... anyone else feel the same way? I saw the +1 from Aahz already. ;-) however, i can understand the original posters inquiry... you just don't see too many FT positions offered that list Python as the sole or major development language. i'm sure folks on the list either get "found" by companies that need Python skills, or, we want to keep those jobs to ourselves and spend time hacking sites to remove those listings. :-) it is also worthy to note that in general, the number of job listings which have the word "Python" in them have risen steadily over the past few years. i guess the "secret" is getting out. just subscribing to dice and monster have let me see this growth on a weekly basis. if you're lucky, one or two of the listings in these weekly lists will contain positions that are pretty much Python-only. cheers, -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list

Folks, I'd like to announce my final Python courses for 2007: Need to get up-to-speed with Python as quickly as possible? Come join me, Wesley Chun, author of Prentice-Hall's well-received "Core Python Programming," for another set of courses this Fall in beautiful Northern California! This will be the final set for 2007... if you miss these, you'll have to wait until next year. I look forward to meeting you! - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (COMPREHENSIVE) INTRODUCTION TO PYTHON: Mon-Wed, 2007 Oct 8-10 This is course is meant for those new to Python and/or want to get more in-depth formal training. We will immerse you in the world of Python in only a few days. We will show you more than just its syntax (which you don't really need a book to learn, right?). Knowing more about how Python works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer coming out of the gate. 3 hands-on labs each day will help hammer the concepts home. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - INTERNET PROGRAMMING WITH PYTHON: Sat, 2007 Oct 13 This 1-day course will introduce current Python programmers to 3 distinct areas of Internet programming, each in self-contained modules with a set of lab exercises following each lecture topic: Network Programming using Sockets -- Underneath all of today's network protocols, i.e., HTTP, FTP, RDBMS, IM, e-mail, etc., lies the main communication mechanism, sockets. Here, we introduce client/server architecture and how to program sockets using Python. Internet Client Programming -- One level above the socket layer are well-known Internet protocols such as FTP, NNTP, POP3, and SMTP. In this section, we learn how to create Internet clients of these protocols to transfer files, send and receive e-mail, and read Usenet newsgroup postings. Web/CGI Programming -- Yes, pure CGI is "sooo yesterday," but before you jump on all the web framework bandwagons, it's a good idea to learn basics and the basis of how all web servers deliver dynamic content back to the client browser so that you can appreciate all the work that is done on your behalf by a more fully-featured frame- work. Time-permitting, we will also give a high-level overview of one of the more popular Python web frameworks, Django. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - WHERE: near the San Francisco Airport (SFO/San Bruno), CA, USA WEB: http://cyberwebconsulting.com (click "Python Training") LOCALS: easy freeway (101/280/380) with lots of parking plus public transit (BART and CalTrain) access via the San Bruno stations, easily accessible from all parts of the Bay Area VISITORS: free shuttle to/from the airport, free high-speed internet, free breakfast and regular evening receptions; fully-equipped suites See website for costs, venue info, and registration.

[ANN] Python courses this Spring
I'll be giving a variety of Python courses this Spring. Daytime courses are for visitors and locals who need Python training in the shortest amount of time possible via consecutive workdays. Python is certainly gaining momentum as our February course filled up completely! Although I had planned on scheduling the same set to be taught in November, it is likely that these May daytime sessions are the last ones of 2007. In contrast, I'm experimenting with a *weekly evening* course in Silicon Valley designed mainly for locals. It represents a viable alternative to those who cannot take time off during the week as well as being more budget-friendly, as I am partnering with a local community college (Foothill) to offer this course. Class takes place on the main campus and you must register through the college to attend. For more information, such as cost and other course details, see the corresponding websites below.

Re: Need help to learn Python
> From: [EMAIL PROTECTED] > Date: 23 Mar 2007 06:20:15 -0700 > > Core Python Programming is mostly theory and very little code. It's > good for reference and digging deeper into the language... let me clarify here that mike's statement refers to the total number of large applications in the book. Core Python *does* have a lot of code in it, but they are mostly snippets and bits using the interactive interpreter. i chose this model instead of many large applications because: 1) i feel that small snippets that people can follow along with in the interpreter is more valuable... in fact, many readers *don't* have the interpreter in front of them, but they can see what it does so that once they *are* in front of it, it does what they expect 2) providing smallish to medium-sized applications allows for maximum absorption by the reader 3) i didn't have time to develop lots of large applications... if you learn with lots of large applications with lots of code, then this book is not for you. with that said, i would still like to state that the book's target audience is for people who know how to program but need to pick up Python as quickly as possible. the "theory" that's in the book is really more explanation of how the Python interpreter works, especially the relationship between objects and memory management. the goal is to give you enough of an understanding of how Python works "under the covers" that you will write very effective code, even as a beginner to the language. you can read more of my "manifesto" on Amazon's page for the book as well as at the book's website below. cheers! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list

Re: [Tutor] Accessing callers context from callee method

> variables or locals() from foo
> so
> def func():

A. python has statically-nested scoping, so you can do it as long as you:
1. define foo() as an inner function -- its def is contained within
func()'s def:
def func():
i = 10
def foo():
print i
2. you don't define a variable with the same name locally. in other
words, you do have access to func()'s 'i' as long as you don't create
another 'i' within foo() -- if you do, only your new local 'i' will be
within your scope.
B. another alterative is to pass in all of func()'s local variables to foo():
foo(**locals())
this will require you to accept the incoming dictionary in foo() and
access the variables from it instead of having them be in foo()'s
scope.
C. in a related note, your question is similar to that of global vs.
local variables. inside a function, you have access to the global as
long as you don't define a local using the same name. should you only
wish to manipulate the global one, i.e. assign a new value to it
instead of creating a new local variable with that name, you would
need to use the "global" keyword to specify that you only desire to
use and update the global one.
i = 0
def func():
i = 10
in this example, the local 'i' in func() hides access to the global
'i'. in the next code snippet, you state you only want to
access/update the global 'i'... IOW, don't create a local one:
i = 0
def func():
global i
i = 10
D. this doesn't work well for inner functions yet:
i = 0
def func():
i = 10
def foo():
i = 20
the 'i' in foo() shadows/hides access to func()'s 'i' as well as the
global 'i'. if you issue the 'global' keyword, that only gives you
access to the global one:
i = 0
def func():
i = 10
def foo():
global i
i = 20
you cannot get access to func()'s 'i' in this case.
E. however, starting in Python 3.x, you'll be able to do somewhat
better with the new 'nonlocal' keyword:
i = 0
print('globally, i ==', i)
def func():
i = 10
print('in func(), i ==', i)
def foo():
nonlocal i
i = 20
print('in foo(), i ==', i)
foo()
print('in func() after calling foo(), i ==', i)
func()
in this case, foo() modified func()'s 'i'.
hope this helps!

Python books out there, and they were special-topic oriented, not ones to learn the language from. it took almost a year and a half to write, but from what i hear from readers and what has been said in reviews, it's pretty comprehensive, and is a good book to learn Python from. i only wish that *i* had it when i was learning! Most "Python experts" do not have the entire language memorized, so everyone has to look at the docs from time-to-time, not just beginners. i'll either hit up http://docs.python.org/library/MODULE.html or flip open my Nutshell or PER references, and finally, i'll google if i have to (rare). the Python docs are the language manuals and not necessarily full reference texts, so you have to just take them for what they are. hope this helps! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 "Python Fundamentals", Prentice Hall, (c)2009 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com -- http://mail.python.org/mailman/listinfo/python-list

Most introductory courses focus on teaching you the syntax and giving you an idea of a language's flow control and data types. However, this can only get your so far. Although our course may appear to be for those new to Python, it is also perfect for those who have tinkered with it and want to "fill in the gaps" or desire more in-depth formal training. It combines the best of both an introduction to the language as well as covering intermediate language fundamentals that can make you more effective, even as a beginner. We will immerse you in the world of Python in only a few days, showing you more than just its syntax (which you don't really need a book to learn, right?). Knowing more about how Python works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer coming out of the gate. Daily hands-on labs will help hammer the concepts home. Come join me, Wesley Chun, author of Prentice-Hall's bestseller "Core Python Programming," for a comprehensive course coming up this Fall in beautiful Northern California to get up-to-speed with Python as quickly and as in-depth as possible!
