I don't really understand what you mean by this. Can you copy and
paste the actual error message (all of it)?

What is the purpose of getattr? Why not just use help or am I completely
misunderstanding this?

However, the example provided is:
li = ['larry', 'curly]
getattr(li, 'pop')
It seems

Why do you use class A: instead of class A(object): ?

Hey Huy,
thanks. But what is the first parameter in this case? (Note there is nothing
here I'm trying to accomplish except understand).
In the original example, 'statsout' is the name of the module. In this case
there is no module so why can you substitute 'output_text'?
thanks,
Pete

You are trying to get a reference to a function in the same

Hi all! I'm here again with a question about introspection.
My module stores a set of functions. I need to know, from another
script, if a particular function of this module "is enabled" (it
means, if it shall be executed by the caller script). I looked for
some introspective builtin/function, but
29 matches
