Pythonpath is a special environment variable that provides guidance to the Python interpreter about where to find various libraries and applications. It is similar to the PATH environment variable in other languages, such as C and Java, but has additional directories for Python modules.
- If Pythonpath is set to a single directory, Python will search for modules and files in that directory only.
- O if Pythonpath is set to a list of directories, Python will search for modules and files in each of those directories.
