|
A small Python library to parse various kinds of time expressions,
|
||
|
|
inspired by
|
||
|
|
`this StackOverflow question <http://stackoverflow.com/questions/4628122/how-to-construct-a-timedelta-object-from-a-simple-string>`_.
|
||
|
|
|
||
|
|
The single function ``pytimeparse.timeparse.timeparse`` defined in the
|
||
|
|
library (also available as ``pytimeparse.parse``) parses time
|
||
|
|
expressions like the following:
|
||
|
|
|
||
|
|
- ``32m``
|
||
|
|
- ``2h32m``
|
||
|
|
- ``3d2h32m``
|
||
|
|
- ``1w3d2h32m``
|
||
|
|
- ``1w 3d 2h 32m``
|
||
|
|
- ``1 w 3 d 2 h 32 m``
|
||
|
|
- ``4:13``
|
||
|
|
- ``4:13:02``
|
||
|
|
- ``4:13:02.266``
|
||
|
|
- ``2:04:13:02.266``
|
||
|
|
- ``2 days, 4:13:02`` (``uptime`` format)
|
||
|
|
- ``2 days, 4:13:02.266``
|
||
|
|
- ``5hr34m56s``
|
||
|
|
- ``5 hours, 34 minutes, 56 seconds``
|
||
|
|
- ``5 hrs, 34 mins, 56 secs``
|
||
|
|
- ``2 days, 5 hours, 34 minutes, 56 seconds``
|
||
|
|
- ``1.2 m``
|
||
|
|
- ``1.2 min``
|
||
|
|
- ``1.2 mins``
|
||
|
|
- ``1.2 minute``
|
||
|
|
- ``1.2 minutes``
|
||
|
|
- ``172 hours``
|
||
|
|
- ``172 hr``
|
||
|
|
- ``172 h``
|
||
|
|
- ``172 hrs``
|
||
|
|
- ``172 hour``
|
||
|
|
- ``1.24 days``
|
||
|
|
- ``5 d``
|
||
|
|
- ``5 day``
|
||
|
|
- ``5 days``
|
||
|
|
- ``5.6 wk``
|
||
|
|
- ``5.6 week``
|
||
|
|
- ``5.6 weeks``
|
||
|
|
|
||
|
|
It returns the time as a number of seconds (an integer value if
|
||
|
|
possible, otherwise a floating-point number)::
|
||
|
|
|
||
|
|
>>> from pytimeparse import parse
|
||
|
|
>>> parse('1.2 minutes')
|
||
|
|
72
|
||
|
|
|
||
|
|
A number of seconds can be converted back into a string using the
|
||
|
|
``datetime`` module in the standard library, as noted in
|
||
|
|
`this other StackOverflow question <http://stackoverflow.com/questions/538666/python-format-timedelta-to-string>`_::
|
||
|
|
|
||
|
|
>>> from pytimeparse import parse
|
||
|
|
>>> import datetime
|
||
|
|
>>> parse('1 day, 14:20:16')
|
||
|
|
138016
|
||
|
|
>>> str(datetime.timedelta(seconds=138016))
|
||
|
|
'1 day, 14:20:16'
|
||
|
|
|
||
|
|
Future work
|
||
|
|
-----------
|
||
|
|
|
||
|
|
1. Give the user more flexibility over which characters to use as
|
||
|
|
separators between fields in a time expression (e.g., ``+`` might
|
||
|
|
be useful).
|
||
|
|
2. Internationalisation?
|
||
|
|
3. Wow, https://github.com/bear/parsedatetime .
