Recently I saw a blogpost on tracking time in Python. This is inspired me to share how I track time in my python scripts. First I put the following python decorator function in my code or preferably import it from a common module.
import time def timeit(method): def timed(*args, **kw): ts = time.time() result = method(*args, **kw) te = time.time() print('%r (%r, %r) %2.2f sec' % (method.__name__, args, kw, te-ts)) return result return timed
You can use the timeit function like this:
@timeit def longRunningOperation(dummyArg, optionalDummyArg=None): time.sleep(3) longRunningOperation("test", "optional test")
The output of the timeit decorator function looks like this:
'longRunningOperation' (('test', 'optional test'), {}) 3.00 sec
As you can see, the timit function reports the function name, the passed arguments and the elapsed time
If you want to learn more about decorator functions I would suggest to read the python.org wiki article on decorators. On the same site there is also an article with useful decorator functions for things like caching, properties, pre- and post conditions, memoization and many more.
