Création d'une bibliothèque Python DateTimeRange qui gère les plages horaires

Je l'ai fait parce que j'en ai besoin de temps en temps.

Installation

pip install DateTimeRange

Usage L'endroit où la chaîne de caractères d'heure est entrée peut être de type datetime.

Création et conversion en chaînes

from datetimerange import DateTimeRange
time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
str(time_range)

'2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900'

Comparaison

from datetimerange import DateTimeRange
lhs = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
rhs = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
print "lhs == rhs: ", lhs == rhs
print "lhs != rhs: ", lhs != rhs

lhs == rhs:  True
lhs != rhs:  False

Déplacer la plage de temps

import datetime
from datetimerange import DateTimeRange
value = DateTimeRange("2015-03-22T10:10:00+0900", "2015-03-22T10:20:00+0900")
print value + datetime.timedelta(seconds=10 * 60)
print value - datetime.timedelta(seconds=10 * 60)

2015-03-22T10:20:00+0900 - 2015-03-22T10:30:00+0900
2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900

Spécification du format de conversion de la chaîne de caractères

time_range = DateTimeRange("2015-03-22T10:00:00+0900", "2015-03-22T10:10:00+0900")
time_range.start_time_format = "%Y/%m/%d"
time_range.end_time_format = "%Y/%m/%dT%H:%M:%S%z"
time_range

2015/03/22 - 2015/03/22T10:10:00+0900
