How can I see the source code for a python library?

I currently find myself using the bs4/BeautifulSoup library a lot in python, and have recently been wondering how it works. I would love to see the source code for the library and don't know how. Does anyone know how to do this?

Solution

The first step is to ask the module itself. Usually its all you need

>>> import bs4
>>> bs4.__file__
'/home/td/anaconda3/lib/python3.7/site-packages/bs4/__init__.py'
>>> exit()
$ pushd /home/td/anaconda3/lib/python3.7/site-packages/bs4
$ ls
builder    diagnose.py  __init__.py  testing.py
dammit.py  element.py   __pycache__  tests
