import atexit
from time import time
from datetime import timedelta

def secondsToStr(t):
    return str(timedelta(seconds=t))

line = "="*40
def log(s, elapsed=None):
    print(line)
    print(secondsToStr(time()), '-', s)
    if elapsed:
        print("Elapsed time:", elapsed)
    print(line)
    print()

def endlog():
    end = time()
    elapsed = end-start
    log("End Program", secondsToStr(elapsed))

def now():
    return secondsToStr(time())

start = time()
atexit.register(endlog)
log("Start Program")

Another method to do this - but not so pythonic - is this:

import time
start_time = time.time()
main()
print("--- %s seconds ---" % (time.time() - start_time))
