import datetime
duration = datetime.timedelta(seconds=1823723)   # 21 days, 2:35:23
days, seconds = duration.days, duration.seconds  # (21, 9323)
hours = seconds // 3600                          # 2
minutes = (seconds % 3600) // 60                 # 35
seconds = (seconds % 60)                         # 23
