simple python function question


Hey, i am a python newb, so dont laugh

Say i have

Code:
contents = ['rat' 'dennis']
and later on..

Code:
def look(object=None): 
        if len(contents) > 0:
I get a global error, contents is not defined.

How can I access the contents list from inside a function?
Thanks

You have crossed into a second "namespace". Named variables don't automatic'ly cross over into the function. In the function, it's looking for the variable contents, but it hasn't been defined in the function. You can have the same name inside and outside the function, with different values.

You can add "global contents" as the first line of the def, and it will use the main variable named contents. Or, you can pass the variable along when you call the function. You are already passing the variable object along, just add in contents.
