Executing periodic actions in Python [duplicate]

Answer 1

This will insert a 10 second sleep in between every call to foo(), which is approximately what you asked for should the call complete quickly.

import time

while True:
    foo()
    time.sleep(10)

To do other things while your foo() is being called in a background thread

import time
import sys
import threading

def foo():
    sys.stdout.write('({}) foo\n'.format(time.ctime()))

def foo_target():
    while True:
        foo()
        time.sleep(10)

t = threading.Thread(target=foo_target)
t.daemon = True
t.start()
print('doing other things...')
