Update All PIP Packages

Revisiting an old Python + Django project made me realize that I needed to upgrade it’s PIP packages. Unfortunately, PIP doesn’t provide a way out of the box to update all of your installed packages at once. To update all of the PIP packages at once, use the following script.

import pip
from subprocess import call
 
for dist in pip.get_installed_distributions():
    call("pip install --upgrade " + dist.project_name, shell=True)
