Question

Where is my pythonpath stored?
When I write

import sys
sys.path

Where does Python get that data?

Answer 1

Python gets that data from the path attribute of the sys module. This path is a list, and if you want to add a new directory to the path, just use the append method.

For instance, to add the directory /home/me/mypy to the path, just do:

import sys
sys.path.append("/home/me/mypy")
