Python Module installation path

Unix (Linux): prefix/lib/pythonx.y/site-packages
Default path:/usr/local/lib/pythonx.y/site-packages

In addition, on unix-like systems, Python's own build-in modules are typically located:
/usr/lib/pythonx.y/site-packages
The command to install the module from the source code is generally: setup.py install
Of course, you can change the default third-party module installation path as needed, and parameters can be added to the command: –user, Or–home, Or–prefix And–exec-prefix, or–install-base and–install-platbase, etc. To specify the installation path.

The installation path of the module must be in the Sys.path list, in order to be able to import in the script normally
