Packages and indices Python: Setting up the environment

At one point, developers realize they want to share their code with other programmers. They can write a library of functions or a ready-made program and then pass it on to others. Programmers usually use packages used in this case.

How packages work

Packages are sets of modules and nested packages. But that's not the only meaning of the term. In a broader sense, a package is a unit of code exchange between developers.

Python packages contain source code and metadata — additional information, including:

  • Purpose of the package
  • The current version of the package and a list of previous versions
  • Compatibility with different versions of Python
  • The license under which creators distribute the package
  • List of package dependencies
