Ich fuhr fort mit MarredCheese's Antwort und fügte hinzu year
, month
, millicesond
y microsecond
alle Zahlen werden als Ganzzahl formatiert, außer für second
und damit den Bruchteil einer Sekunde kann angepasst werden .
@kfmfe04 fragte nach Sekundenbruchteilen, also habe ich diese Lösung gepostet
In der main
gibt es einige Beispiele.
from string import Formatter
from datetime import timedelta
def strfdelta(tdelta, fmt='{D:02}d {H:02}h {M:02}m {S:02.0f}s', inputtype='timedelta'):
"""Convert a datetime.timedelta object or a regular number to a custom-
formatted string, just like the stftime() method does for datetime.datetime
objects.
The fmt argument allows custom formatting to be specified. Fields can
include seconds, minutes, hours, days, and weeks. Each field is optional.
Some examples:
'{D:02}d {H:02}h {M:02}m {S:02.0f}s' --> '05d 08h 04m 02s' (default)
'{W}w {D}d {H}:{M:02}:{S:02.0f}' --> '4w 5d 8:04:02'
'{D:2}d {H:2}:{M:02}:{S:02.0f}' --> ' 5d 8:04:02'
'{H}h {S:.0f}s' --> '72h 800s'
The inputtype argument allows tdelta to be a regular number instead of the
default, which is a datetime.timedelta object. Valid inputtype strings:
's', 'seconds',
'm', 'minutes',
'h', 'hours',
'd', 'days',
'w', 'weeks'
"""
