Hello List sys.path contains all paths where python shall look for libraries.
Eg on my system, here is the content of sys.path: >>> import sys >>> sys.path ['', 'C:\\Users\\jean-marc\\Desktop\\python', 'C:\\Program Files\\Python36-32\\python36.zip', 'C:\\Program Files\\Python36-32\\DLLs', 'C:\\Program Files\\Python36-32\\lib', 'C:\\Program Files\\Python36-32', 'C:\\Program Files\\Python36-32\\lib\\site-packages'] The last path is used as a location to store libraries you install yourself. If I am using a virtual environment (with venv) this last path is different 'C:\\Users\\jean-marc\\Desktop\\myenv\\lib\\site-packages' I looked for windows environment variables to tell python how to fill sys.path at startup but I didn't found. So how does it work ? -- https://mail.python.org/mailman/listinfo/python-list
