sorting question

Hi, I've had a look at http://wiki.python.org/moin/HowTo/Sorting, but am not sure if I can get the operator.itemgetter to do what I want for my particular need. I'm also not sure why creating my own cmp for pulling tuple parts out and passing it to a list sort doesn't just work. I'm sure th

Thanks to all. I had suspected this was the best way to go, but as I'm fairly new to Python, it seemed worth a check. --b On Mar 23, 2007, at 12:48 PM, [EMAIL PROTECTED] wrote: > On Mar 23, 1:20 pm, belinda thom <[EMAIL PROTECTED]> wrote: >> On Mar 23, 2007, at 11:04

exit to interpreter?

Hi, I'm writing a function that polls the user for keyboard input, looping until it has determined that the user has entered a valid string of characters, in which case it returns that string so it can be processed up the call stack. My problem is this. I'd also like it to handle a special

class / instance question

Hello, I'm hoping the Python community knows whether or not the following is possible, and if it is possible, how I would go about writing code to do this. I've written two game classes---Nim and TicTacToe---where each derives from a Game class that I've created (it is essentially an abst

checking one's type

Hi, I've been using the following hack to determine if a type is acceptable and I suspect there is a better way to do it: e.g. if type(s) == type("") : print "okay, i'm happy you're a string" If anyone knows a better way, I'm all ears. Thanks, --b -- http://mail.python.org/mailman/lis

doctesting

Hi, I'd like to write a tester script that I can place in one place (say ~/bin/python/tester.py) and then have it visible to me at the cmd- line (by setting the path variable appropriately). I have had no luck in getting it to work, however. It appears like the doctest code itself assumes t
