--- title: Sleep How Can I Make a Time Delay in Python --- ## 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, '')) ```
