How to get the difference between two dates in hours, minutes and seconds.? [duplicate]

Finally found solution

import datetime
data1 = datetime.datetime.now()
data2 = datetime.datetime.now()

diff = data2 - data1

days, seconds = diff.days, diff.seconds
hours = days * 24 + seconds // 3600
minutes = (seconds % 3600) // 60
seconds = seconds % 60
