learning python
Hi all, I was just wondering about good books that teach python (either with programming or no programming experience at all) ? Or some online tutorial? Thanks -- http://mail.python.org/mailman/listinfo/python-list

list problem
Hi all,
I have two lists that contain strings in the form string + number for
example
>>> list1 = [ ' XXX1', 'XXX2', 'XXX3', 'XXX5']
the second list contains strings that are identical to the first list,
so lets say the second list contains the following
>>> list1 = [ ' XXX1', 'XXX2', 'XXX3', 'XXX6']
and now what ive been trying to do is find the first string that is
available,
i.e a string that is in neither of the two lists so the following code
should only print XXX4 then return.
for i in xrange(1,10):
numpart = str(1) + str("%04i" %i)
str = "XXX" + numpart
for list1_elm in list1:
if list1_elm == str:
break
else:
for list2_elm in list2:
if list2_elm == str:
break
else:
print str
return

But there may be other characters before XXX (which XXX is constant). A
better example would be, that string s is like a file name and the
characters before it are the absolute path, where the strings in the
first list can have a different absolute path then the second list
entries. But the filenames are always exact. So you need to split the
entries bases on "\\" (windows machine) and match on this ?

subprocess module
Hi all, ive been trying to create a thumbnail using the ffmpeg converter running the ffmpeg.exe using the subprocess module with the following code >>> import subprocess >>> p = subprocess.Popen(["ffmpeg.exe -i video.mpg", "-f mjpeg -ss 5 -vframes >>> 1 -s 160x120 -an video.gif"], shell=True, stdout=subprocess.PIPE) but the ffmpeg complains about the input file being corrupter, whereas when i run the same command via the command shell (cmd.exe) it works.

non-blocking PIPE read on Windows
Hi all, I have been looking into non-blocking read (readline) operations on PIPES on windows XP and there seems to be no way of doing this. Ive read that you could use a Thread to read from the pipe, but if you still use readline() wouldnt the Thread block too? What i need to do is, create a process using subprocess.Popen, where the subprocess outputs information on one line (but the info continuesly changes and its always on the same line) and read this information without blocking, so i can retrieve other data from the line i read in then put this in a GUI interface. readline() blocks until the newline character is read, but when i use read(X) where X is a number of bytes then it doesnt block(expected functionality) but i dont know how many bytes the line will be and its not constant so i cant use this too. Any ideas of solving this problem? Cheers -- http://mail.python.org/mailman/listinfo/python-list

using the subprocess module to create a subprocess and piping the
stdout,stdin and stderr so you wont see any ouput from the process
unless you read from the PIPE's.
import subprocess
p = subprocess.Popen("x.exe", shell=True,
stdout=subprocess.PIPE,stdin=subprocess.PIPE, stderr=subprocess.PIPE)

What is that thing in Software Engineering (SE) ? that it is hard to find simple solutions (or any problem in life for that matter) I remember last year at uni we had to write this program (get information from user save it somewhere) for a SE assignment. And half the teams went off and used MySql to save data retrieved from the user via a GUI. And in no part of the requirements document did it write ; * Customer requires GUI frontend * Customer needs MySql databases server usage to store data So my team created a Command Line Program (i.e cmd module in python) as the UI and used object Serialization (pickling in python) to files. So we finished in half the time that other teams took (and many had to drop the database server usage in the end) and stressed like tomorow was Judgement Day. Oh yeah we designed our application so that it was easy to create a GUI or change the Serialization to saving stuff into a database and we had one of the top marks out of all the teams. So OP, if you really dont need to embed bash inside wxPython, then dont and use what Philippe suggested, unless its in the requirements :) Cheers -- http://mail.python.org/mailman/listinfo/python-list

loop until keypress (Windows XP)
Hi all,
Im using the cmd module and i have command that loops and keeps on
printing text, what i want to be able to do is loop until the user
presses a particular key, say Q/q ? I tried the following code;
line = raw_input ("press q to abort")
while line[0] != "q":
""" keep printing text """
line = raw_input ("press q to abort")
but raw_input blocks for input until the newline char. So i then tried
the following code
import sys
chr = sys.stdin.read(1)
while chr != "q":
""" keep printing text """
chr = sys.stdin.read(1)
but again this blocks too.
is there a way to do this, wait for user input but dont block? I could
use a thread that just does the previous code block but i already have
three Thread classes, its just getting too complex with threads!
Cheers

i did try it in a Python shell after i learnt what it was. Like i said
*args will be a list, but when i try **args with the following code it
doesnt work
def test(**args):
keys = args.keys()
for key in keys:

HTTP server
Hi all, Ive been reading about creating a HTTP server like the one pydoc creates (and studying pydoc source code). What i want to know, is it possible to create server that creates a webpage with hyperlinks that communicate back to the HTTP server, where each link accessed tells the server to execute some arbitrary command on local machine its running on?

Im having trouble running the following cgi script on windows
#!c:/Python/python.exe -u
text = """Content-type: text/html
CGI 101
A Second CGI script
Hello, CGI World!
"""
print text
using this http server from
http://effbot.org/librarybook/cgihttpserver.htm
import CGIHTTPServer
import BaseHTTPServer
class Handler(CGIHTTPServer.CGIHTTPRequestHandler):
cgi_directories = ["/cgi"]
PORT = 8000
httpd = BaseHTTPServer.HTTPServer(("", PORT), Handler)
print "serving at port", PORT
httpd.serve_forever()
i get the error number 403, when i try to access the cgi script which
is located in a subdirectory called cgi where this file is (http
server). I have a feeling that i need to change the Handler class or
something, implement , but i couldnt find any examples other then this
from eff-bot.
It could also be this line of code, that a google search turned up, its
the way of running cgi scripts on windows
#!c:/Python/python.exe -u

I dont think the OP wants to do post-install configuration (i may be
wrong! ) but to change for example some config file.
You should be able to create a dictionary containing username=password,
then iterate over this dictionary and use os.system("xterm -e telnet -u
%s -p %s") where -u is username and -p is password (im not quite sure
if telnet has these arguments or if it works like this too)

Dont know about converting vbs to python but using Tim Golden's wmi
module to trap the event of a new process starting is easy.
wmi module can be found at http://timgolden.me.uk/python/wmi.html
>>> import wmi
>>> c = wmi.WMI()
>>> watcher = c.watch_for (
>>> notification_type="Creation"
>>> wmi_class="Win32_Process"
>>> delay_secs=2,
>>> Name='calc.exe'
>>> )
>>> calc_created = watcher ()
>>> print calc_created
and if you want to trap closing down of processes then change
notification_type to "Deletion"
-Cheers

Well to watch for multiple process at the same time you need to use Threads and have written one found at http://www.google.com/notebook/public/14017391689116447001/BDUsxIgoQkcSO3bQh > Or even how could I query what the value of the attribute Name is equal > to in the object calc_created from the example above?

Oh yeah you are correct, i forgot about possible rehashing after assignment operation, so to that means you do need to use a lock to restrict only one thread at time from accessing the dictionary. Again i recommend using a Queue to do this.

Password, trust and user notification
Hi all, I was going to write this script for a friend that notifies him via logging onto his Gmail account and sending him an email to his work email about some events occurring in the execution of the script. If you enter your password into a script as input how can someone trust the programmer that he will not send a email to himself containing his password? Assuming this person does not know anything about programming and this person knows nothing about programming ethics. This is coming from the fact that i need to notify the user in someway that does not require her to constantly watch the execution of the script, for example when a user signs in to Windows Live Messenger pop up.

So do you want to remove "&" or replace them with "&" ? If you want
to replace it try the following;
import urllib, sys
try:
location = urllib.urlopen(url)
except IOError, (errno, strerror):
sys.exit("I/O error(%s): %s" % (errno, strerror))
content = location.read()
content = content.replace("&", "&")
To do this with BeautifulSoup, i think you need to go through every
Tag, get its content, see if it contains an "&" and then replace the
Tag with the same Tag but the content contains "&"
Hope this helps.

I did something similar, read in text file format it to 79 characters
and print it out to a multiple images of 480x272 so i could read them
on my PSP. Anyway the code to handle the formatting (even though this
is one column of 78 characters with one character space from the top
and bottom, and sides)
corpus = open("essay.txt","r")
wordcount = 0
pctline = ""
pctlines = [
for line in corpus.readlines():
# i dont need the newline character as it will be printed onto
images
line = line[:-1]
# i want individual words where each word is separated by a space
character
words = line.split(" ")
for word in words:
if wordcount + len(word) + 1 < 78:
wordcount = wordcount + len(word) + 1
pctline = pctline + word + " "
else:
wordcount = len(word)
pctlines.append(pctline)
pctline = None
pctline = word + " "
corpus.close()
what it does is keeps a list of words and iterate through it and see if
the length of that word and one space character and the line doesn't
exceed 78, if it doesnt then add it to the pctlines, add the count to
the wordcount + 1. If it does then we have one line either 78
characters long or less and add it to pctlines which is a list of all
the lines.
Hope this helps.

These elements appeared like; \ipsupport\ipbuild\Wizard\build.pl@@\main\buildmods\3 these elements are then checked againts previously submitted merge requests to see if there are any merge requests that require the same elements to be merged too. When the elements are read from the stdout pipe of the subprocess the backslashes aren't escaped and because these "paths" aren't real windows paths non of the os.path... path escaping methods work! Well i've solved the problem just by using pycleartool "links directly against ClearCase libraries" which returns a tuple containing (status,output,error) and the element paths in output are properly escaped.

Did you even read the problem description? oops...i did read the problem description, but i when i tried the code it worked for me and when i put spaces into the TextArea it wasn't reflected correctly back. So i thought this was the problem. Adrian, can you still try replacing spaces with via the following; #!/usr/bin/python import cgi import urllib import cgitb cgitb.enable() print "Content-type: text/html\n" form = cgi.FieldStorage() #print urllib.quote_plus(form["essay"].value) for char in form["essay"].value: if char == ' ': print " " else: print char Cheers -- http://mail.python.org/mailman/listinfo/python-list

Hi all, I'm looking for anyone who is working on a project at the moment that needs help (volunteer). The last project i worked on personally was screen-scraping MySpace profiles (read more at the following link) http://placid.programming.projects.googlepages.com/screen-scrapingmyspaceprofiles but that didn't go all to well, so im kinda bored and need something to do, with Python. So any suggestions anyone? Cheers -- http://mail.python.org/mailman/listinfo/python-list
