Use simple schedule module in python

. 1  Import Schedule
 2  Import Time
 . 3  
. 4  DEF Start ():       # define a function 
. 5      Print ( " **** " )
 . 6  
. 7  
. 8  IF  the __name__ == ' __main__ ' :
 . 9      schedule.every (2) .seconds.do ( start)   # it means every 2 seconds to perform a start function 
10      the while True:   # here is the definition of an infinite loop 
. 11          schedule.run_pending () // each two second interval to check that no
 12 is          the time.sleep (. 1) // this is to allow the program to sleep for a few seconds

 

In addition to performing a function may be the number of seconds interval, the interval may be how many minutes, hours

1, two hours interval

schedule.every(2).hours.do()

2, two minutes interval

schedule.every(2).minutes.do()
