In Python, you can use time.sleep(seconds) to make the current executing Python program to sleep or delay a few seconds.

import time

time.sleep(1) # delays for 1 seconds
time.sleep(10) # delays for 10 seconds
time.sleep(60) # delays for 1 minute
time.sleep(3600) # delays for 1 hour

Full example.

test_delay.py

import time

def main():

    while True:
        print("DateTime " + time.strftime("%c"))
        time.sleep(1) # delays for 1 seconds

if __name__ == '__main__':
    main()

Output

DateTime 09/22/15 18:03:42
DateTime 09/22/15 18:03:43
DateTime 09/22/15 18:03:44
DateTime 09/22/15 18:03:45
DateTime 09/22/15 18:03:46
DateTime 09/22/15 18:03:47
