What 2 Time?

Reusable timing code that handles unit conversion, pretty printing time, total of repeat and (in future) re-entrant timers.

A timer can be creted and will default to printing total time on stopping:

>>> from what2_time import Timer
>>> t = Timer().start()
>>> t.stop()
Elapsed time: 1.8890 seconds

Or given a name for ease of inspection

>>> from what2_time import Timer
>>> t = Timer("FooTime").start()
>>> t.stop()
FooTime - Elapsed time: 1.4432 seconds

Alternatively, the output can be logged to any callable such as a logger:

>>> from what2_time import Timer
>>> import logging
>>> logger = logging.getLogger()
>>> logging.basicConfig(level=10)
>>> t = Timer(logger=logger.info).start()
>>> t.stop()
INFO:root:Elapsed time: 1.2577 seconds

Or instead set no logger and handle logging yourself:

>>> from what2_time import Timer
>>> t = Timer(logger=None).start()
>>> elapsed = t.stop()
>>> print(elapsed)
1.587853118

A timer can also be used as a context manager:

>>> import time
>>> from what2_time import Timer
>>> with Timer("ContextTimer"):
...     time.sleep(1)
ContextTimer - Elapsed time: 1.0004 seconds

If you want to time the total time of something that is not performed in a single block, instead a MetaTimer can be used:

>>> import time
>>> from what2_time import MetaTimer
>>> with MetaTimer("MetaT"):
...     time.sleep(1)
...
>>> with MetaTimer("MetaT"):
...     time.sleep(1)
...
>>> print(MetaTimer.get_meta_duration("MetaT"))
2.00162006

Note - the package doesn't attempt to protect against multiple timers with the same name running in parallel - yet.
