Sleep How Can I Make a Time Delay in Python

The time module in the Python standard library contains the function sleep() which suspends a program for a given number of seconds.

Example:

import time

for letter in 'hello, world!':
    print(letter)
    time.sleep(2)  # sleep 2 seconds between each print

When using sleep, you can define the amount of time that the program is suspended using either an integer (a whole number) or a float (a number with decimal places), depending on the level of control you want over the time that the program sleeps. For example, time.sleep(10) would suspend a program for 10 seconds, while time.sleep(5.5) would suspend a program for five and a half seconds.

More Information

Time module documentation on the sleep function.

Another method to achieve a time delay will be by using selenium related waits, which can be either implicit wait or waiting until an expected condition. Implicit Wait

from selenium import webdriver

#below code initializes a chrome webdriver, and we can apply waits using it  
    driver = webdriver.Chrome('driver_path')
    driver.implicitly_wait(5)

Wait until Excpected Condition

self.wait.until(EC.presence_of_element_located((By.ID, '<Id of the element you are waiting for>'))
