Sleep, Wait or Pause Python Code for Seconds with time.sleep()

To add a delay to your Python code you can use the sleep() function from Python's time module.

import time

countdown = [3, 2, 1, 'Go!!!']

for item in countdown:

# 3
# 2
# 1
# Go!!!

The sleep module takes a single argument. This can be either an integer for the number of seconds to sleep or a float if you want to have sub-second resolution such as 0.5 of a second, 1.75 seconds and so on. Using the sleep() function suspends the processing of the thread which uses almost no processing power and allows other processes to run while it sleeps.
