In Python 2:

import mymodule
# make some changes

But be careful that objects attached to the module are *not* updated to 
use the new module!

import mymodule
x = mymodule.MyClass()

x still uses the old version of the class and method, and will *not* use 
the new one. You have to throw it away and start again:

x = mymodule.MyClass()

Now you will see the new behaviour.

In Python 3, everything is the same except you have to do:

from imp import reload
