Convert A Datetime.timedelta Into ISO 8601 Duration In Python?
Answer : Although the datetime module contains an implementation for a ISO 8601 notation for datetime or date objects, it does not currently (Python 3.7) support the same for timedelta objects. However, the isodate module (pypi link) has functionality to generate a duration string in ISO 8601 notation: In [15]: import isodate, datetime In [16]: print(isodate.duration_isoformat(datetime.datetime.now() - datetime.datetime(1985, 8, 13, 15))) P12148DT4H20M39.47017S which means 12148 days, 4 hours, 20 minutes, 39.47017 seconds. This is a function from Tin Can Python project (Apache License 2.0) that can do the conversion: def iso8601(value): # split seconds to larger units seconds = value.total_seconds() minutes, seconds = divmod(seconds, 60) hours, minutes = divmod(minutes, 60) days, hours = divmod(hours, 24) days, hours, minutes = map(int, (days, hours, minutes)) seconds = round(seconds, 6) ## build date date = '' if days: d...
