I can not do it in the form such that it has deducted the time from today to an example; 2021: 04: 05 in the form of hours: minutes: seconds
from datetime import datetime, time
leaving_date = datetime.strptime('2021-04-05 00:00:00', '%Y-%m-%d %H:%M:%S')
now = datetime.now()
print(str"%d hours, %d minutes, %d seconds")
Could someone improve my code and help me? thanks
