[Tutor] Newbie question: join() string method

Re: [Tutor] Newbie question: join() string method

Hi, I am not sure what 'random' does (what package is it from?), but list=['1','2','3'] slist=','.join(list) works, while list=[1,2,3] slist=','.join(list) does not. It appears 'join' only works on lists (and maybe tuples?) of string objects and the list must be passed in as an argument. Tr

Ha! Thanx for all the input everybody. I finally got it to work. The contents of the list is now stored in the file without the []. The solution is in the code below. Next step in my learning process is reading the file contents and storing it in a dictionary. One question: When I run the prog

Re: [Tutor] __init__.py for running a file from commandline?

Marcus, When you type something from the command-line, you are at the whims of the WinXP command shell. You have to follow its rules, not Python's. It would need to have "python" in %PATH%, and then it would need to have to run "python C:\path\to\pyroot\utils\commands\mygrep.py". The arguments
