Simultaneous run of python loops from cron

I've a script with a loop for some minutes. It starts at 9:30AM and it runs a loop (time.sleep(120)) and then re-execute the script) for a variable amount of time (max 2h).

Now I would like to run a second script (at the same hour) which does the same: starts a loop for a variable amount of time.

Will the 2 loops conflict? Can I run 2 loops of python3 at the same time or I need any particular command to run them as different processes (like the & in bash)?

Solution

use the threading module. The following executes print_cube and print_square simultaneously.

import threading 
  
def print_cube(num): 
    """ 
    function to print cube of given num 
    """
    print("Cube: {}".format(num * num * num)) 
  
def print_square(num): 
    """ 
    function to print square of given num 
    """
    print("Square: {}".format(num * num)) 
  
if __name__ == "__main__": 
    # creating thread 
    t1 = threading.Thread(target=print_square, args=(10,)) 
    t2 = threading.Thread(target=print_cube, args=(10,)) 
  
    # starting thread 1 
    t1.start() 
    # starting thread 2 
    t2.start() 
  
    # wait until thread 1 is completely executed 
    t1.join() 
    # wait until thread 2 is completely executed 
    t2.join() 
  
    # both threads completely executed 
    print("Done!")

You can also use apscheduler, but it will run the processes separately.

from apscheduler.scheduler import Scheduler

# Start the scheduler
sched = Scheduler()
sched.start()

# Schedule job_function to be called every two hours
@sched.interval_schedule(hours=2)
def job_function():
    print ("Hello World")

    time.sleep(120)
    print ("my second script")
