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?

Try the inspect module.

// m

I would start with "dir (moduleName)"

e.g the module os



... if type(v) == types.BuiltinFunctionType or\
... type(v) == types.BuiltinMethodType or\
... type(v) == types.FunctionType or\
... type(v) == types.MethodType:
... print '%-20s: %r' % (k,type(v))

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

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:
types.BuiltinMethodType,
types.FunctionType,
types.MethodType,)
if isinstance(v, FUNCTION_TYPES):
print '%-20s: %r' % (k,type(v))

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.
