Project Description


pip install readabledelta

Usage examples

The readabledelta is just a more human-friendly printable version of timedelta. The public interface is equivalent to timedelta (with the exception of the years kwarg in the constructor - see below). Only printing behaviour has been modified.

>>> lunchtime = datetime(year=2015, month=5, day=27, hour=12)
>>> right_now = datetime(year=2015, month=5, day=27, hour=13, minute=5)
>>> delta = right_now - lunchtime
>>> print 'We had lunch {} ago'.format(delta)
We had lunch 1:05:00 ago

Oh, what’s that mean an hour and five minutes? Or it’s a minute and five seconds?

>>> rdelta = readabledelta.from_timedelta(delta)
>>> print 'We had lunch {} ago'.format(rdelta)
We had lunch 1 hour and 5 minutes ago

There are often contexts where you don’t really care about the sign of the delta, only the absolute value. But if you are not careful to handle the future or past tense correctly, you get this:

>>> print 'Lunchtime and now are {} apart'.format(lunchtime - right_now)
Lunchtime and now are -1 day, 22:55:00 apart

Huh?? Well, it’s technically correct that lunchtime and now are negative one day plus 22 hours and 55 minutes apart. But we don’t generally think in terms of negative time just as we don’t think in terms of negative lengths; 5 minutes in the future and 5 minutes in the past are both just 5 minutes away.

>>> rd = readabledelta.from_timedelta
>>> print 'Lunchtime and now are {} apart'.format(rd(lunchtime - right_now))
Lunchtime and now are 1 hour and 5 minutes apart

A readabledelta is a timedelta, compares as you’d expect, and is simple enough not to misbehave.

>>> issubclass(readabledelta, timedelta)
>>> isinstance(rdelta, timedelta)
>>> rdelta == delta

This means you can safely add or subtract them to datetime instances.

Long deltas

Python doesn’t have great support for “long” deltas, the years kwarg was missing for example.

>>> readabledelta(years=1, days=2) == timedelta(days=367)
>>> print readabledelta(years=1, seconds=126)
1 year, 2 minutes and 6 seconds

And if you’re a human being you don’t care about displaying microseconds.

>>> startup_time = datetime(year=2013, month=1, day=1)
>>> now = datetime.utcnow()
>>> print 'The server has been up for {}'.format(now - startup_time)
The server has been up for 876 days, 8:16:35.116488
>>> print 'The server has been up for {}'.format(rd(now - startup_time))
The server has been up for 2 years, 146 days, 8 hours, 16 minutes and 35 seconds
