Binary package “python3-isoduration” in ubuntu oracular

Operations with ISO 8601 durations (Python 3 package)

 ISO 8601 supports time durations in string format, for example
 "P3Y6M4DT12H30M5S" represents a duration of 3 years, 6 months, 4 days,
 12 hours, 30 minutes, and 5 seconds. This package supports working
 with such durations, addressing the shortcomings of the isodate package.
