In order to prevent the problem of two modules importing each other, Python only imports all modules once by default. If you need to re-import the module,

Python2.7 can use reload() directly, and Python3 can use the following methods:

Method 1: Basic method

from imp import reload

reload(module)

Method 2: Follow the routine, you can do this

import imp

imp.reload(module)

Method 3: Look Looking at imp.py, I found something, so it can also be like this

import importlib

importlib.reload(module)

Method 4: According to the laws of nature, of course it can also be like this

from importlib import reload

reload(module)
