Where does pip install its packages?

Question

I activated a virtualenv which has pip installed. I did

pip3 install Django==1.8

and Django successf

Answer 1

One can import the package then consult its help

import statsmodels
help(sm)

At the very bottom of the help there is a section FILE that indicates where this package was installed.

This solution was tested with at least matplotlib (3.1.2) and statsmodels (0.11.1) (python 3.8.2).
