How do I get time of a Python program's execution?

Question

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

Answer 1

time.clock()

Deprecated since version 3.3: The behavior of this function depends on the platform: use perf_counter() or process_time() instead, depending on your requirements, to have a well-defined behavior.

time.perf_counter()

Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide.

time.process_time()

Return the value (in fractional seconds) of the sum of the system and user CPU time of the current process. It does not include time elapsed during sleep.

start = time.process_time()
... do something
elapsed = (time.process_time() - start)
