A.3 Installing Python modules and packages
PyPI is the “Python Package Index” and contains over 300,000 modules and
packages that you can download and import
. You can browse and search
this catalog at
https://pypi.org/
The pip application downloads and manages
PyPI packages on your system. Use either pip
or pip3
from the command
line to start the application. I refer to pip
in what follows to demonstrate
several of its capabilities. When you run these commands, your output will likely be different
from what I show here because I have other packages installed. If you are curious, I list the
Python packages on my machine in Appendix F, Production Notes.
