how to “reimport” module to python then code be changed after import

Question

I have a foo.py

def foo():
    print \"test\"

In IPython I use:

In [6]:  import foo
In [7]:  foo.foo()
test
         


        

Answer 1

For Python 2.x

reload(foo)

For Python 3.x

import importlib
import foo #import the module here, so that it can be reloaded.
importlib.reload(foo)
