Find path of module without importing in Python

by

Using pkgutil module:

>>> import pkgutil
>>> package = pkgutil.get_loader("pip")
>>> package.filename
'/usr/local/lib/python2.6/dist-packages/pip-0.7.1-py2.6.egg/pip'
>>> package = pkgutil.get_loader("threading")
>>> package.filename
'/usr/lib/python2.6/threading.py'
>>> package = pkgutil.get_loader("sqlalchemy.orm")
>>> package.filename
'/usr/lib/pymodules/python2.6/sqlalchemy/orm'

In Python 3, use pkgutil.get_loader("module name").get_filename() instead.

Using imp module:

>>> import imp
>>> imp.find_module('sqlalchemy')
(None, '/usr/lib/pymodules/python2.6/sqlalchemy', ('', '', 5))
>>> imp.find_module('pip')
(None, '/usr/local/lib/python2.6/dist-packages/pip-0.7.1-py2.6.egg/pip', ('', '', 5))
>>> imp.find_module('threading')
(<open file '/usr/lib/python2.6/threading.py', mode 'U' at 0x7fb708573db0>, '/usr/lib/python2.6/threading.py', ('.py', 'U', 1))

N.B: with imp module you can’t do something like imp.find_module('sqlalchmy.orm')
