Python Shell和execfile范围

Question

I'm working from inside an ipython shell and often need to reload the script files that contain my functions-under-construction.

Inside my main.py I have:

def myreload(): execfile("main.py") execfile("otherfile.py")

Calling myreload() works fine if I have already ran in the same ipython session the execfile commands directly.

However, for some reason, if the session is fresh and I just called execfile("main.py"), then myreload() doesn't actually make the functions from inside otherfile.py available. It doesn't throw any error though.

Any ideas?

Answer 1

Functions create a new scope. execfile() runs the script in the current scope. What you are doing will not work.

Answer 2

If you seek to learn the actual correct usage of ipython (ie in interactive mode), then you should use magic commands like:

%run

and

%edit

Check help for those functions with %run? . This provides explicit examples.
