18.4 Changing the Module Search Path

In Chapter 15, we mentioned that the module search path is a list of directories initialized from environment variable PYTHONPATH, and possibly .pth path files. What we haven't shown you until now is how a Python program can actually change the search path, by changing a built-in list called sys.path (the path attribute in the built-in sys module). sys.path is initialized on startup, but thereafter, you can delete, append, and reset its components however you like:

>>> import sys

>>> sys.path
