What sets up sys.path with Python, and when?

by

Most of the stuff is set up in Python’s site.py which is automatically imported when starting the interpreter (unless you start it with the -S option). Few paths are set up in the interpreter itself during initialization (you can find out which by starting python with -S).

Additionally, some frameworks (like Django I think) modify sys.path upon startup to meet their requirements.

The site module has a pretty good documentation, a commented source code and prints out some information if you run it via python -m site.
