Fast I/O Implementation For Python 3.x

Hello, I See That Some C++(Others Also) Programmers Use Different I/O Methods.

  1. Like Reading From File And Outputting To File.
  2. Making Custom Stdin Reader.
  3. How Do I Implement The Above Two Methods in Python 3.x?
    Thank You

You can replace some of the standard functions like…

from sys import stdin, stdout
input = stdin.readline
# Your code goes here
stdout.writeline(ans, '\n')

This will help you to pass the time limit almost every time.
