Re: Python Programming Challenges for beginners?
Codechef and all those algorithmic websites aren't very good for python because, quite frankly, python is definitley slower than C or C++. You should probably pick up a project on sourceforge or freshmeat if you feel confident enough.

Re: editor with autocompletion
If you're actually going to release this, you shouldn't bundle it with a preexisting text editor (IMHO) in case it goes out of development and then you'll end up like DSL (damn small linux) did. In other words either you get a text editor that's basically never going out of development (emacs, not vim since its not that well grounded) and write extensions for it, OR, write your own text editor. Second option is very highly time consuming.

Open source projects

Just drawing lines and plotting points?
Hello, I need a python library that makes drawing lines and plotting points (these two things are the only things I need to do) easy. Or, how can I do something like this with pygame? Basically, what I want to do is make graphs. In pygame, since the coordinate system switches the x's and the y's I would have to switch them again when I plot my points so my graphs look okay.

Multiple files
I was trying to write a program with just one class and it was working fine.

Project euler (in case you don't know: projecteuler.net) I'm trying to do the third one and here's my current code: 1 def checkPrime (x): 2 factors=2; 3 while factors<=x: 4 if x==factors: 5 return True; 6 elif x%factors==0: 7 return False; 8 elif x%factors!=0: 9 factors=factors+1; 10 11 factorl=[]; 12 factors=600851475142; 13 14 while factors != 1: 15 if 600851475143%factors==0: 16 if checkPrime(factors)==True: 17 print factors; 18 else: 19 factors=factors-1; 20 21 else: 22 factors=factors-1; 23 And it just gets frozen when I run it. I put a print "Loop completed" in one of the loops and it showed up just fine. So, there are two possibilities: 1. Its looping in the trillions and taking a while 2. I have a forever loop somewhere -- http://mail.python.org/mailman/listinfo/python-list
Re: Project euler no. 3
But, I'm returning true or false right?

Re: Podcast catcher in Python
C shouldn't be very hard. You just get the url of the file you want to connect to, then just use the normal connect sequence and read the file and print it out to the UNIX shell, then at the unix shell, just pipe it to an MP3. Or you could just do it with FILE *.

IRC bot
I"m trying to write an IRC bot just for fun (in python of course). Here's my
current code:
1 #!/usr/local/bin/python
2 import time
3 import socket
4
5 def message (x, channel,s):
6 y="PRIVMSG"+" "+ channel+" :"+x
7 s.send(y);
8 host="irc.freenode.net";
9 port=6667;
10 size=1024;
11 channel="#dhaivatrocks";
12 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM);
13 s.connect((host,port));
14 s.send("NICK PoincareBot");
15 s.send("USER PoincareBot 8 * : Paul Mutton");
16 time.sleep(5);
17 s.send("JOIN #dhaivatrocks");
18 s.send(PRIVMSG #dhaivatrocks :Hello everybody!
19 while True:
20 pass;
21
What I don't understand is that it doesn't display any messages or show a
new message login on my IRC client. What's wrong with my code?
