Question

I have a program say:

for i in xrange(10):
    for p in xrange(10):
        print i, p

I would like to be able to print the time in milliseconds that the program took to execute at the end of the program.

I’ve written a small snippet that could allow you to measure the elapsed time using a context manager. Have a look at https://github.com/BaltoRouberol/timer-context-manager

Example:

from timer import Timer

with Timer() as t:
    # Some code we want to time

print t.elapsed_ms  # elapsed time, in milliseconds

It uses timeit.default_timer (a platform specific timer function :time.time for Unix platforms and time.clock for Windows platforms) to measure the wall clock time of the block.
