How to list all functions in a Python module?

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

Once you've imported the module, you can just do:

help(modulename)

... To get the docs on all the functions at once, interactively. Or you can use:

dir(modulename)

... To simply list the names of all the functions and variables defined in the module.

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.
