How to list all functions in an imported module?

[Kamilche]

I can't figure out how to list all functions from an imported module.
I searched Google, but all the answers I found didn't work. Did
something change in Python 2.2, perhaps there's a new method of doing
it?

I would start with "dir (moduleName)"

Try the inspect module.

Yuck... wouldn't using "callable(v )" be a lot nicer?

It depends whether he wants to include callable classes or really does want
just functions.

If he doesn't want callable classes, then a nicer way would be to use
isinstance, which also gives you the option of factoring out the list of
types:
[color=blue][color=green][color=darkred]
>>> FUNCTION_TYPES = (types.BuiltinF unctionType,[/color][/color][/color]
types.BuiltinMe thodType,
types.FunctionT ype,
types.MethodTyp e,)
[color=blue][color=green][color=darkred]
>>> for k,v in os.__dict__.ite ms():[/color][/color][/color]
if isinstance(v, FUNCTION_TYPES) :
print '%-20s: %r' % (k,type(v))

Re: How to list all functions in an imported module?

Thanks guys. It DOES work, as you stated... my problem was I had a
module called the same name as a variable I was using, yeesh.

I'm used to C, where you have to declare variables before use, and the
compiler catches stuff like this. I might have to go back to a
Hungarian-like naming conventions for variables, it appears.
