Apart from timeit which ThiefMaster mentioned, a simple way to do it is just (after importing time):
t = time.time()
# do stuff
elapsed = time.time() - t
I have a helper class I like to use:
class Timer(object):
def __init__(self, name=None):
self.name = name
def __enter__(self):
self.tstart = time.time()
def __exit__(self, type, value, traceback):
if self.name:
print('[%s]' % self.name,)
print('Elapsed: %s' % (time.time() - self.tstart))
It can be used as a context manager:
with Timer('foo_stuff'):
# do some foo
# do some stuff
Sometimes I find this technique more convenient than timeit - it all depends on what you want to measure.
