Since you aren't familyer with classes i will keep this within the scope of functions... If you have code like this
def a(): def b(): a+=1 Then you can only call function b when you are within function a James On Jan 22, 2008 8:58 PM, <[EMAIL PROTECTED]> wrote: > I'm still learning Python and was wanting to get some thoughts on this.
