a straight forward statement timer for Python

timeit.py

@contextmanager
def timeit():
    """ straight forward statement timer for Python
    
    Usage:
        with timeit() as timer:
            ...
            
        print(timer.elpased()) # prints the timedelta, timer also has .start, .end
    """
    from datetime import datetime as t
    class timer: elapsed = None
    tx = timer()
    t0 = dt.now()
    yield tx
    t1 = dt.now()
    tx.start = t0
    tx.end = t1
    tx.elapsed = t0 - t1

    

I just got tired of writing code like this:

t0 = datetime.datetime.now()
# do something to measure time for
...
# end  of something
t1 = datetime.datetime.now()
elapsed = t0 - t1

I'm sure someone else has already written that contextmanager, but couldn't be bothered with finding it :-)
