You can import the module and check the module.__file__ string. It contains the path to the associated source file.

Alternatively, you can read the File tag in the the module documentation, which can be accessed using help(module), or module? in IPython.

from distutils.sysconfig import get_python_lib
print(get_python_lib())

Linux users can find the locations of all the installed packages like this:

pip list | xargs -exec pip show
