Error: No module named ‘fcntl’

I get the following error:

Traceback (most recent call last):
  File "C:/Users/aaaa/Desktop/ttttttt.py", line 5, in <module>
   import reload
  File "C:\Users\aaa\AppData\Local\Programs\Python\Python36\lib\site-
packages\reload.py", line 3, in <module>
    import sys, time, re, os, signal, fcntl
ModuleNotFoundError: No module named 'fcntl'

So I did a pip install, which also gets an error.

    C:\Users\aaaa>pip install fcntl
    Collecting fcntl
      Could not find a version that satisfies the requirement fcntl (from versions: )
No matching distribution found for fcntl

Search results cPython, hacking, routing and many other words are coming out.

It’s a tough answer for beginners, so I want to get a more detailed solution.

How should I solve it?

#py3
import time
from selenium import webdriver
import codecs
import sys
import reload
import re
import fcntl
import os
import signal
