Time expression parser

Project description

A small Python library to parse various kinds of time expressions, inspired by this StackOverflow question.

The single function timeparse defined in the module 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.timeparse import timeparse
>>> timeparse('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:

>>> from pytimeparse.timeparse import timeparse
>>> import datetime
>>> timeparse('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 .
