Best practice is to put all the imports at the beginning of the module,

so they are easy to spot.

If you put an import inside a function, it gets re-executed each time
the
function is called, which is a waste of time. Not too much, since import
first checks sys.modules to see if it's already loaded.

Also, avoid the from xxx import * form, as it pollutes the
namespace. And it makes it hard to figure out where a particular name is
declared.

I believe these and other best practices can be found in pep8.

http://www.python.org/dev/**peps/pep-0008/

yeah, I read pep8.
However I find in the file path/to/djcelery/loaders.py from django-celery
source, there are so many import/from statements used inside functions, I
do not know why the author coded like this. Are there any special facts?



I can't speak for django or django-celery. There are people that
disagree on this, and there are some reasons to override the ones I
mentioned. One would be large modules that are not used in most
circumstances, or not used till the program has run for a while.

If you put the import inside a function, you can save on startup time by
deferring some of the logic till later. And if there's a module that
probably won't be used at all (eg. an error handler), perhaps you can
avoid loading it at all.

I still think readability trumps all the other reasons, for nearly all
programs. Only once you decide you have a performance problem should you
change that.



There's a thread on the dev ml about imports that also discusses startup 
times for anyone who's interested.

Can a simple byte count help here? Copy the whole file with FTP. From

Then parse the smaller file, extracting whole records for use by (C).
That way you can just keep the unparsed tail (partial record I imagine)
around for the next fetch.

Looking at RFC959 (the FTP protocol):

  http://www.w3.org/Protocols/rfc959/4_FileTransfer.html

it looks like you can do a partial file fetch, also, by issuing a REST
(restart) command to set a file offset and then issuing a RETR (retrieve)
command to get the rest of the file. These all need to be in binary mode
of course.

So in principle you could track the byte offset of what you have fetched
with FTP so far, and fetch only what is new.

Yes, this sounds good. Provided the mv is on the same filesystem.

For example: "mv /tmp/foo /home/username/foo" is actually a copy and not
a rename because /tmp is normally a different filesystem from /home.

Ha. I used to be very bad at testing, now I am improving and am merely
weak.

One approach to testing is to make a mock up of the other half of the
system, and test against the mockup.

For example, you have code to FTP new data and then feed it to (C). You
don't control the server side of the FTP. So you might make a small mock
up program that writes valid (but fictitious) data records progressively
to a local data file (write record, flush, pause briefly, etc). If you
can FTP to your own test machine you could then treat _that_ growing
file as the remote server's data file.

Then you could copy it progressively using a byte count to keep track of
the bits you have seen to skip them, and the the

If you can't FTP to your test system, you could abstract out the "fetch
part of this file by FTP" into its own function. Write an equivalent
function that fetches part of a local file just by opening it.

Then you could use the local file version in a test that doesn't
actually do the FTP, but could exercise the rest of it.

It is also useful to make simple tests of small pieces of the code.
So make the code to get part of the data a simple function, and write
tests to execute it in a few ways (no new data, part of a record,
several records etc).

There are many people better than I to teach testing.

The following is just a guess.

I copy the files to a convenient location and then specify that
location to setup.py. Below is an excerpt from my build process.

mkdir c:\src\lib
mkdir c:\src\include
xcopy /Y mpir.h c:\src\include\*.*

I don't think so. pyCrypto probably builds a single DLL so the MPIR library is
statically linked into that DLL. Only the innvocation of setup.py should need
to refer to the MPIR library locations.  I don't use pip so I'm not sure how to
get pip to install the resulting DLL, etc.

Python's indices were designed for these kinds of shenanigans.

def rotated(seq, n):
"""Iterate through all of seq, but starting from index n.

>>> ", ".join(str(n) for n in rotated(range(5), 3))
'3, 4, 0, 1, 2'

i = n - len(seq)
while i < n:
yield seq[i]
i += 1

if __name__ == "__main__":
import doctest
doctest.testmod()

If you have merely an iterable instead of a sequence, then look
to some of the other clever stuff already posted.

PyDev not saving Ipython History between sessions

[Wanderer]

One feature I like about Ipython is that it saves the history between
sessions. The history isn't saved if you close Ipython with the corner
X, but if you type 'exit()' it is saved. This doesn't work when using
Ipython as the console in Pydev. Do I have something setup wrong? Is
there a different command than exit() I should use before closing a
session in PyDev. Is there a command to load the history when I start
a session?

Naming convention for in-house modules (Newbie question)

[HoneyMonster]

I am quite new to Python (2.7 on Linux), and have built a few modules 
using wxPython/wxGlade for GUI elements and Psycopg2 for database access. 
I adhere mostly to the PEP8 guidelines, and use Pylint to help with 
quality control.

So far I have been *very* impressed. Due to Python's straightforwardness 
and the wealth of documentation, results have been excellent.

Here is my question: I would like to start an in-house library of small 
modules to import, for things like error handling/logging. That's easy 
enough, but is there a recommended way of naming such modules? I am 
concerned about avoiding name clashes with standard modules and site 
packages.

Thanks.

Let me do a recap with application analogies:

You want a combination of

   - github / bitbucket for source management *et ce terra*
   - http://readthedocs.org/ for documentation and search
   - http://nullege.com for code search
   - http://repos.io/ for the social features

I think it's not enough for fully integrated project management solution, I
will add this features:

   - Paragraph level and document level comments for documentation like
   http://djangobook.com/
   - Matrix comparaisons : grid feature of http://djangopackages.com/
   - Dependency tracking, library usage in a nice visual way
   - Ask for review thingy
   - Buildbot et all
   - Q/A system
   - Mailling lis
   - Bounties
   - Agenda because time lapse
   - Blogs because it's all the rage
   - CLI interface so that hipsters can hypergrep all the way
   - A big fat red button to promote good libraries into the standard lib
   - A specialized reader UI for hypernerds so that they can cope with that
   much information while still pretending to be human

And when the Python WAR-like format is done, automatic deployement of web
application on the Python.org cloud powered by machines using a pure Python
implemention of the HURD on top a green chips running PyPy.

You could put all the modules under a single package; then you only
need to worry about avoiding 1 name conflict.

Don't use raw SQL strings in the first place. Use a proper

cursor.execute("insert into reviews(message, title) values (%s, %s)",
 ("We don't know where to go", "We can't wait till morrow"))


  Yes.  You are doing it wrong.  Do NOT use the "%" operator when
putting SQL queries together.  Let "cursor.execute" fill them
in.  It knows how to escape special characters in the input fields,
which will fix your bug and prevent SQL injection.

Komodo 7 release (Python development tools)

[Todd Whiteman]

Hello,

My name is Todd. I'm the lead developer for Komodo IDE (Interactive 
Development Environment) and Komodo Edit (a free, open-source editor) at 
ActiveState. I wanted to announce that the newest version, Komodo 7, has 
been released:


http://www.activestate.com/komodo-ide

Python has long been one of the main languages supported by Komodo, so 
we're always getting useful feedback and suggestions. For Komodo 7, 
we've incorporated a lot of this feedback into enhancing our Python 
features.


* Python Code Profiling (IDE only)
  Users have asked if there is a way to find out why their programs are 
taking so long to run. Komodo IDE 7 can show a graph of the methods and 
calls made by your program, so that you can detect where your CPU is 
being taken up.


* Sophisticated Syntax Checking
  Choose between multiple syntax checkers like PyLint, PyFlakes and 
PyChecker. Provides language-specific syntax checking for 
CSS/JavaScript/Django inside HTML template languages like Django.


* Code Collaboration (IDE only)
  We wanted to make pair programming easier. With the collaboration 
feature, multiple users can edit a document at the same time. It's kind 
of like Google Docs, but for code editing!


* Speed
  With Komodo 7 you'll notice a lot snappier Komodo start-up time, 
lower CPU utilization - particularly when idle, and lower memory usage 
for large projects.


* Even more...
  There are way more features in Komodo 7 than I can outline in a 
single post, so check out the online web pages for more Komodo 7 
enhancements:


http://www.activestate.com/komodo-ide/python-editor

Again, note that Komodo comes in two different flavours:

  1) Komodo Edit - completely free and fully open-source editor, 
offering smart code completions, syntax checking, code colorizing, 
sophisticated editing and more.


  2) Komodo IDE - a full featured IDE, offering advanced debugging, 
interactive shells, code browsing, source code control, database 
integration, unit testing, regular expression tools and more.


Try out Komodo 7 and let me know what you think. We really appreciate 
the support and feedback!


Cheers,
Todd

How to make PyDev pep8 friendly?

[Ali Zandi]

Hi,

I was trying to find a way to configure PyDev e.g. in Eclipse to be
pep8 friendly.

There are a few configurations like right trim lines, use space after
commas, use space before and after operators, add new line at the end
of file which can be configured via Eclipse -> Window -> Preferences -
> PyDev -> Editor -> Code Style -> Code Formatter. But these are not
enough; for example I couldn't find a way to configure double line
spacing between function definitions.

So is there any way to configure eclipse or PyDev to apply pep8 rules
e.g. on each save?

Thanks,

frozendict

[Evan Driscoll]

Hi all,

I've been trying for a few days (only a little bit at a time) to come up
with a way of implementing a frozendict that doesn't suck. I'm gradually
converging to a solution, but I can't help but think that there's some
subtlety that I'm probably missing which is why it's not already provided.

Does anyone know why Python doesn't already come with a frozendict, or
why there seem to only be a couple attempts to write one?

Because there is no way to implement one that doesn't suck?

Because it's a solution in search of a problem?



Actually, that's unfair. A write-once dict would be awesome for providing 
read-only constants, if only there were some way to set a namespace to 
using non-builtin dicts.

Define "doesn't suck".  If I were to hack one up, it would look
something like this:


from collections import Mapping, Hashable


class frozendict(Mapping, Hashable):

def __init__(self, *args, **kwargs):
self.__dict = dict(*args, **kwargs)

def __len__(self):
return len(self.__dict)

def __iter__(self):
return iter(self.__dict)

def __getitem__(self, key):
return self.__dict[key]

def __hash__(self):
return hash(frozenset(self.__dict.iteritems()))

def __repr__(self):
return 'frozendict(%r)' % (self.__dict,)


Not extensively tested, but it seems to work pretty well for me.

Ian

Yes, the idea is "lazy importing" -- add the module name to the namespace, 
but don't actually load it until necessary. Apparently it is used heavily 
in Django and by PyPy.

Interestingly, the CPython developers are currently migrating the low-
level import machinery from C to pure Python (or at least mostly pure 
Python), because

(1) the C code is a mess and practically nobody understands it; 
(2) the exact import behaviour is very hard to explain; 
(3) consequently Jython, IronPython etc. may behave slightly differently;
(4) and they'd like to share the same code base as CPython; and
(5) it's really hard to write custom importers.

Moving to a pure Python implementation should fix these problems, 
provided that the speed hit isn't too big.

http://sayspy.blogspot.com.au/2012/02/how-i-bootstrapped-importlib.html


One suggestion made is that Python should support lazy imports out of the 
box.

Another reason for putting imports inside a function is that global 
imports are, well, global. If you only need access to a module from one 
function, why pollute the global namespace?

A reason for *not* importing inside a function is that there can 
sometimes be strange effects with threads, or so I've been told, but I 
couldn't begin to explain exactly what (allegedly) can go wrong.


> I still think readability trumps all the other reasons, for nearly all

Which is a good reason for importing inside a function: why confuse the 
reader with a global import if it isn't needed globally?

For the same reason there are frozensets?

I put dicts in sets all the time.  I just tuple the items, but that
means you have to re-dict it on the way out to do anything useful with
it.  I am too lazy to write a frozendict or import one, but I would
use it if it was a builtin.

Id of methods

Hell All,

I am trying to see if I could get more of Python without being insane.

class Boo(object):

def __init__(self , moon, sun):
self.moon = moon
self.sun = sun
def daf(self):
return self.sun + self.moon
def ball(self):
return self.sun * self.moon


print Boo.__dict__

{'__module__': '__main__', 'ball': , 'daf':
, '__dict__ ..}

print  hex(id(Boo.daf))
0x27de5a0



My question is why is it that the id of Boo.daf  is different from daf's
hex value in the above dict?

If you have a sequence, and don't mind copying it, the easiest way is 
just to slice and join:


>>> a = range(20)
>>> b = a[5:] + a[:5]
>>> print b
[5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 0, 1, 2, 3, 4]

Short, sweet, easy and simple. What's not to like about it?

For small (say, less than a few thousand of items) sequences, this 
probably is the fastest way to do it. 

Handling this lazily is trickier than it seems, because you have to store 
the first N items somewhere until you get to the rest of the iterable. 
There is no Right Way to do it, since the best solution will depend on 
how many items you have and how large N is.

Here's one way with itertools:


>>> from itertools import islice, chain, tee
>>> a = iter(range(20))
>>> t1, t2 = tee(a)
>>> b = chain(islice(t1, 5, None), islice(t2, None, 5))
>>> print list(b)
[5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 0, 1, 2, 3, 4]

But read the docs for tee first: it may be that converting to a list is 
faster and more memory efficient.

http://docs.python.org/library/itertools.html#itertools.tee


Using tee may be overkill. Here's a simpler way:

>>> a = iter(range(20))
>>> t = list(islice(a, 5))
>>> b = chain(a, t)
>>> list(b)
[5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 0, 1, 2, 3, 4]

If your data is truly humongous, already stored in a list, and you don't 
want to make a copy, then I recommend your trick of generating the 
indexes:

def cycle(seq, n):
for indexes in (xrange(n, len(seq)), xrange(n)):
for i in indexes:
yield seq[i]

If your data is humongous but only available lazily, buy more memory :)

Take no notice of the exact value of id(). It is an opaque value that
shouldn't be relied upon for anything.

That said, though, I tried your example in my two Windows Pythons,
2.6.5 and 3.2; in 3.2, the behavior is most like what you seem to be
accepting:

>>> Boo.__dict__
dict_proxy({'__module__': '__main__', 'ball': , 'daf': , '__dict__':
, '__weakref__': , '__doc__': None, '__init__':
})
>>> hex(id(Boo.daf))
'0xfcbc90'
>>> Boo.daf


Same number everywhere. But 2.6.5 has a difference that might give you a hint:

>>> print Boo.__dict__
{'__module__': '__main__', 'ball': ,
'daf': , '__dict__': , '__weakref__': , '__doc__': None, '__init__': }
>>> Boo.daf


daf is not a function, it's a special object for an unbound method.
The exact identity of it is not necessarily useful; and buried inside
it is the actual function that you defined:

>>> hex(id(Boo.daf))
'0x11b5c10'
>>> hex(id(Boo.daf.im_func))
'0x11bdc30'

And that seems to be the number that's given in the repr().

But mainly, don't rely on id() for anything beyond uniqueness against
all current objects.

Because you are using Python 2. Just print Boo.daf and you will see that 
it is not a 'function'. In Python 3, it will be, and have the same address.

Or if you have a huge iterable and only need a small index into it,
snag those first few entries into a list, then yield everything else,
then yield the saved ones:

def cycle(seq,n):
seq=iter(seq)
lst=[next(seq) for i in range(n)]
try:
while True: yield next(seq)
except StopIteration:
for i in lst: yield i

>>> list(cycle(range(10,20),2))
[12, 13, 14, 15, 16, 17, 18, 19, 10, 11]

Requires storage space relative to n, regardless of the length of the iterator.

As I've said in another reply they keep talking about pyramid as if
that will be a totally new framework. I'm not saying I know things
definitely but surely my impression was that the team is out for
something new not based on turbogears 2.

Yep, it is :)

The development team keeps talking about pyramid which is supposed to
be a totally new framework. I don't pretend to understand the work
flow but surely they got me confused about switching gears (no pun
intended!).

How about cherrypy?

I've wanted to do that as well.

My current use case is I want to have a dict as an attribute of another
object, and I want to use that object as a key in a dictionary. That
means that the outer object has to be immutable (an obnoxious enough
task on its own, BTW) and that either the dict itself has to be excluded
from computing the hash or the dict also has to be immutable.


Also, it's not like it has to be a builtin, per se. I know how to spell
'import'. :-)

So part of my objection was that I wanted to make sure I got all of the
expected functionality, and that takes a bunch of functions. I didn't
know about the ABTs in 'collections' though, so that helps a bit.

However, I'd still prefer something that guaranteed immutability better
than that. I might just be fighting the language too much at that point
though...

Can not get the result of query in pymssql module of python...

[amarjeet yadav]

Hi All,
   This is my first post to any mailing group. I am QA engg and
using python for testing automation. I need to connect with Mysql
(2008) and mssql databases for executing some queries.

I have installed following modules & softwares in python 2.7 :

python 2.7.2
setuptools
MySQLdb Module
pymssql module
yum install mysql msql-devel freetdf

I have installed freetds 0.9version. After installation of all the above
components, I have done following things

Python 2.6 (r26:66714, Apr  8 2010, 08:46:35)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymssql
>>> conn = pymssql.connect(host='mssql_server', user='_username',
password='_password', database='_db',as_dict=True)
>>> cur = conn.cursor()
>>> cur.execute('select count(*) from D2.dbo.abc (nolock)')
>>> print cur.fetchall()
[]
>>> cur.rowcount
-1
>>> exit()

I am expecting that the result of the query will be 16. But it is not
retuning any data from query with no error at any place. On execting the
same query in tsql, I got result as 16.
