#    I needed to print time deltas in a compact hours, minutes seconds format for log output. 
#    As an example try these on the Python console:

#    >>> pretty_time_delta(123)
#    '2m3s'
#    >>> pretty_time_delta(12345)
#    '3h25m45s'
#    >>> pretty_time_delta(1234567)
#    '14d6h56m7s'
    
#    It only displays to second precision and only displays up to hours as the largest unit. 
#    To convert a standard Python [`datetime.timedelta`](http://docs.python.org/3/library/datetime.html#datetime.timedelta), use the [`total_seconds()`](http://docs.python.org/3/library/datetime.html#datetime.timedelta.total_seconds) method on your `timedelta` to convert to seconds. 
#    If all your calls come from standard Python `datetime` operations, you probably want to change line 3 to something like:

#     seconds = abs(int(seconds.total_seconds()))

#    The built-in string representation of a `timedelta` is also quite acceptable for most situations and also handles sub-second precision (see the last example):

#     >>> import datetime
#     >>> str(datetime.timedelta(seconds=123))
#     '0:02:03'
#     >>> str(datetime.timedelta(seconds=12345))
#     '3:25:45'
#     >>> str(datetime.timedelta(seconds=1234567))
#     '14 days, 6:56:07'
#     >>> str(datetime.timedelta(seconds=123.456789))
#     '0:02:03.456789'

#     The version included in `python-pretty-time-delta-positive-only.py` has the negative number handling stripped out for some slightly simpler code.
