    \item Modules are Python files (\texttt{.py}) that contain
      functions, classes, and variables.

    \item They allow you to organize and reuse code.
    \item \texttt{import} is used to include modules.
    \item \texttt{from ... import ...} is used to import specific
      elements from a module.
