Variables and none?

[Ivan Shevanski]

Alright first of all I'd like to say I'm a python noob.

Now that thats over with, heres what I'd like to know about.  Is there a
python way to detect if a variable exsists?  Say I had a program that needed
a certain variable to be set to run and the variable was not found when it
came time to use it. . .Would I just have to catch the error, or could I
have python look for the variable beforehand?



Thanks,

-Ivan
