How do I reload a module after changing it?

Question

Python Console with Python 3.4.2

I defined a function in a module which runs correctly in Python Console in PyCharm Community Edition 4.5.4:
ReloadTest.py:

Answer 1

Get it to work!
Instead of from Module import function, I should import the whole module import Module, then call the function by Module.function(). This is because

from ReloadTest import reloadtest

and

importlib.reload(ReloadTest)

can't go together.

>>> import ReloadTest
>>> ReloadTest.reloadtest(1)
Version A: 1

After making changes:

>>> importlib.reload(ReloadTest)

>>> ReloadTest.reloadtest(2)
Version B: 2
