Erstellt eine Python-Bibliothek DateTimeRange, die Zeitbereiche verarbeitet

Ich habe es gemacht, weil ich es von Zeit zu Zeit brauche.

Installation

pip install DateTimeRange

Usage Der Ort, an dem die Zeitzeichenfolge eingegeben wird, kann vom Typ datetime sein.

Erstellung und Konvertierung in Strings

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'

Vergleich

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

Zeitbereich verschieben

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

time_range

2015-03-22T10:00:00+0900 - 2015-03-22T10:15:00+0900

Schneiden Sie den Zeitbereich ab

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

print "before truncate: ", time_range
time_range.truncate(10)
print "after truncate:  ", time_range

before truncate:  2015-03-22T10:00:00+0900 - 2015-03-22T10:10:00+0900 (0:10:00)
after truncate:   2015-03-22T10:00:30+0900 - 2015-03-22T10:09:30+0900 (0:09:00)
