Writing to a certain line?
I was wondering if there was a way to take a txt file and, while keeping most of it, replace only one line. See, I'd have a file like: Tommy 555 Bob 62 Joe 529 And I'd want to set it to be: Tommy 555 Bob 66 Joe 529 Is there any easy way to do this? -- http://mail.python.org/mailman/listinfo/python-list

Umm... I tried using this method and it froze. Infiinite loop, I'm
guessing.

pysqlite error: Database locked?
I'm currently working on a casino script for an IRC bot. I was going to
make a flat file database, but I decided to make it sqlite after some
suggestions. I'm using pysqlite.
http://pastebin.com/764315 < Source. The lines that have @@ (pastebin
doesn't like me) in front of them are important.

Running External Commands + Seeing when they are Finished
I'm currently working on a script that I will run when I leave my computer on at night. It runs external commands like Ad-Aware, Spybot, AVG, Avast, and the like. The problem is, I want to know how to make it so that one command starts only after the last one finishes. When I run them, they end up running all at once! Can someone please tell me if this is possible? Judging from what I've seen in Python's versitility, I bet it can... -- http://mail.python.org/mailman/listinfo/python-list
Re: Running External Commands + Seeing when they are Finished
The problem is with that (which is what I'm doing already) is that one app is in a window and one app is on the command line. Thus, you end up with both apps running at the same time. Are there any modules that have functions for checking when windows are opened or closed? -- http://mail.python.org/mailman/listinfo/python-list
