initializing interactive mode

[Skaperen]

Here is a third untested way, if you don't want to define PYTHONSTARTUP (I never define permanently python-related environment variables). In file usercustomize.py write this

# in usercustomize.py
import sys
if hasattr(sys, 'ps1'): # we are in interactive mode
    with open('spam.py') as ifh:
        exec(ifh.read(), vars(sys.modules['__main__']))

could i just put some other code in place of open+exec lines, under the test for interactive, to do what i want to happen in interactive?

can file usercustomize.py be put in the user's home directory?
