Question

I have a simple module and a basic def. Module name is example315.py and the def is

def right_justify(s)
    print(s)

This works fine when I import example315 and then call example315.right_justify(“hello world”)

If I change my def to not return anything (in fact I can change it in any way) and then run the function again (AFTER saving my module of course) iit still does the print.

Short of exiting IDLE and starting over I can’t seem to get it to work.

Any help appreciated

Answer 1

The module is loaded once per session, you have to re-load it when you change it.

From the Python tutorial on modules:

For efficiency reasons, each module is only imported once per
interpreter session. Therefore, if you change your modules, you must
restart the interpreter – or, if it’s just one module you want to test
interactively, use reload(), e.g. reload(modulename).
