Python sleep()

 import time 
time.sleep(2)
 print("Wait until 2 seconds.") # Output: Wait until 2 seconds.

Python sleep() Syntax

 time.sleep(seconds)

Here, time is a Python module that provides several time-handling methods.

sleep() Parameters

The method takes a single parameter:

• seconds - the number of seconds for which the program will suspend

sleep() Return Value

The method does not return any value.

Example: sleep() Method

 import time print("Printed immediately.") time.sleep(2.4) print("Printed after 2.4 seconds.")

Output

 Printed immediately. Printed after 2.4 seconds.

Here's how the above program works:

1. "Printed immediately" is printed.
2. time.sleep(2.4) suspends execution for 2.4 seconds.
3. "Printed after 2.4 seconds" is printed.

Create a Digital Clock in Python

 import time while True: # get current local time as structured data current_time = time.localtime() # format the time in 12-hour clock with AM/PM formatted_time = time.strftime("%I:%M:%S %p", current_time) print(formatted_time) time.sleep(1)

Output

 01:47:43 PM 01:47:44 PM 01:47:45 PM 01:47:46 PM ... ... ...

In the above example, we obtain and print the current local time inside an infinite while loop.

Then, the program waits for 1 second before repeating the same process.
