I have a command line program in Python that takes a while to finish. I want to know the exact time it takes to finish running.
I\'ve looked at the timeit
I really like Paul McGuire's answer, but I use Python 3. So for those who are interested: here's a modification of his answer that works with Python 3 on *nix (I imagine, under Windows, that clock()
should be used instead of time()
):
#python3
import atexit
from time import time, strftime, localtime
from datetime import timedelta
def secondsToStr(elapsed=None):
if elapsed is None:
return strftime("%Y-%m-%d %H:%M:%S", localtime())
else:
return str(timedelta(seconds=elapsed))
def log(s, elapsed=None):
line = "="*40
print(line)
print(secondsToStr(), '-', s)
if elapsed:
print("Elapsed time:", elapsed)
print(line)
print()
def endlog():
end = time()
elapsed = end-start
log("End Program", secondsToStr(elapsed))
start = time()
atexit.register(endlog)
log("Start Program")
If you find this useful, you should still up-vote his answer instead of this one, as he did most of the work ;).
