Python reload module method

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 one: basic method

from imp import reload

reload(module)

Method two: follow the routine, you can do this

import imp

imp.reload(module)

method Three: Take a look at imp.py and find something, so you can also do this

import importlib

importlib.reload(module)

Method 4: According to the laws of nature, of course you can also do this

from importlib import reload

reload(module)
