PYTHONPATH serves as an environment variable within the Python programming language, empowering users to define supplementary directories for Python to search when seeking modules and packages. This variable serves as a search path and helps Python locate the necessary files to import when executing code. By setting the PYTHONPATH variable, users can extend the default search path and customize the module search behavior according to their needs. This feature enables developers to organize and structure their Python projects efficiently, facilitating easier module importation and enhancing code reusability.
