Is there a standard way to list names of Python modules in a package?

Is there a standard way to list names of Python modules in a package?

Using python2.3 and above, you could also use the pkgutil module:

>>> import pkgutil
>>> [name for _, name, _ in pkgutil.iter_modules([testpkg])]
[modulea, moduleb]

EDIT: Note that the parameter for pkgutil.iter_modules is not a list of modules, but a list of paths, so you might want to do something like this:

>>> import os.path, pkgutil
>>> import testpkg
>>> pkgpath = os.path.dirname(testpkg.__file__)
>>> print([name for _, name, _ in pkgutil.iter_modules([pkgpath])])

import module
help(module)

Maybe this will do what youre looking for?

import imp
import os
MODULE_EXTENSIONS = (.py, .pyc, .pyo)

def package_contents(package_name):
    file, pathname, description = imp.find_module(package_name)
    if file:
        raise ImportError(Not a package: %r, package_name)
    # Use a set because some may be both source and compiled.
    return set([os.path.splitext(module)[0]
        for module in os.listdir(pathname)
        if module.endswith(MODULE_EXTENSIONS)])
