C# and Python
Hi, I am a newcomer in Python. I am going to write a small Python application that will run in windows xp. This application needs to have GUI. Is it possible to make a C# application using visual studio 2005 that will call the python scripts? Let me explain more here: My program will generate a text file of 100 - 10 random integers, and sort those using various sorting methods. Now I have written separate sorting scripts in Python (quick sort, insertion sort etc.). But I want to write the GUI and number generation program in C#.net. When the user clicks Quick Sort button, the quicksort.py will be called and it will sort the numbers. regards, Subeen -- http://mail.python.org/mailman/listinfo/python-list

Well, you don't need to worry about code, you can just copy paste the code of the hit counters available for free.

firefox cache & Python
Hi, I have got into an interesting problem. Today I found that if I type "about:cache?device=disk" (without the quotes) in the address bar of firefox, it displays disk cache information. Now I am thinking to write a Python program that will read this cache info. My initial idea is to somehow save the page in a file and parse it. But how to save the page without human intervention (pressing ctrl+s) :) ? Hope I could make it clear what I am trying to do... Any clue? regards, Subeen. http://love-python.blogspot.com/ -- http://mail.python.org/mailman/listinfo/python-list

Re: global variables: to be or not to be
Another way to avoid using global variables is to return more than one values from the function. Here is an example that may help you to understand it: def foo(a, b, c): a += c b += c return a, b a = 5 b = 10 c = 2 print a, b a, b = foo(a, b, c) print a, b regards, Subeen. http://love-python.blogspot.com/ On Feb 23, 9:11 am, icarus <[EMAIL PROTECTED]> wrote: > I've read 'global variables' are bad.

It really doesn't matter whether you use Perl or Python for writing web crawlers. I have used both for writing crawlers. The scenarios you mentioned (I/O issues, Efficiency, Compatibility) don't differ two much for these two languages. Both the languages have fast I/O. You can use urllib2 module and/or beautiful soup for developing crawler in Python. For Perl you can use Mechanize or LWP modules. Both languages have good support for regular expressions. Perl is slightly faster I have heard, though I don't find the difference myself. Both are compatible with *nix. For writing a good crawler, language is not important, it's the technology which is important. regards, Subeen. http://love-python.blogspot.com/ -- http://mail.python.org/mailman/listinfo/python-list

Trouble sending / receiving compressed data (using zlib) as HTTP POST to server (in django)
Hi, I am trying to send compressed data to a server written in django. But it shows error while decompressing the data in the server. After some experiment I found that the server is not receiving the exact data I am sending. data = 'hello, this is a test message this is another message' data = zlib.compress(data) # now it looks like: x��HQ(��,V�D���T�p^~IFjL �e # length is 45 in django (view) I receive it: data = request.POST['data'] # now it looks like: xQ(�,V�D���^~IFjL �e # length is 34 Can anybody help me understand the issue and how to get over? thanks, Subeen. http://love-python.blogspot.com -- http://mail.python.org/mailman/listinfo/python-list

I am trying to send the data using following code:
...
opener = urllib2.build_opener()
opener.addheaders = [
('User-Agent', 'python'),
('Content-Type', 'application/octet-stream'),
]
data = zlib.compress(data)
params = urllib.urlencode({'uid': uid, 'reqid': rid, 'data':
data})
usock = opener.open(url, params)
resp = usock.read()
usock.close()
...
regards,
Subeen.
