How to list all functions in a Python module?

Question

I have a Python module installed on my system and I'd like to be able to see what functions/classes/methods are available in it.

I want to call the help function on each one. In Ruby I can do something like ClassName.methods to get a list of all the methods available on that class. Is there something similar in Python?

eg. something like:

from somemodule import foo print(foo.methods)  # or whatever is the correct method to call 

Answer 1

You can use dir(module) to see all available methods/attributes. Also check out PyDocs.

Answer 2

Use the inspect module:

from inspect import getmembers, isfunction  from somemodule import foo print(getmembers(foo, isfunction)) 

Also see the pydoc module, the help() function in the interactive interpreter and the pydoc command-line tool which generates the documentation you are after. You can just give them the class you wish to see the documentation of. They can also generate, for instance, HTML output and write it to disk.
