libraries

the name package and library is often used interchangeably

install and import

packages need to be installed, e.g. from https://pip.pypa.io/en/stable/installation/

packages need to be imported, but often only actually needed moduls are imported

the import happens via the command terminal of your computer

  python3 -m pip install package_name #install a package (pip stands for preferred installer programm)

PyPI

PyPI is the python package index

https://pypi.org/

import #imports a package

  import package_name as my_name #imports a package with an assigned name
