Reloading modules in Python

The reload() is a previously imported module. If you’ve altered the module source file using an outside editor and want to test the updated version without leaving the Python interpreter, this is helpful. The module object is the return value.

Reloading modules in Python2.x

For above 2. x and <=Python3.3

import imp
imp.reload(module)

Reloading modules for >=Python3.4 and above

import importlib
importlib.reload(module)
