Finding total hours between two dates in Python

In python, if we try the difference between 2 datetime objects, result will be the number of days between the 2 dates plus the extra seconds.
Using this we can find the number of hours, minutes or seconds between the dates given.
Sample below.

import datetime

startdate = datetime.datetime(2022, 1, 1, 14, 00, 00)
enddate = datetime.datetime(2022, 1, 2, 15, 10, 30)

difference = (enddate - startdate)

totalhours = (difference.days * 24) + (difference.seconds // 3600)
print(totalhours)

totalminutes = (difference.days * 24 * 60) + (difference.seconds // 60)
print(totalminutes)

totalseconds = (difference.days * 24 * 60 * 60) + difference.seconds
print(totalseconds)

Output: 25 1510 90630

For dates in string format, convert to the datetime objects and then find the difference.

import datetime

sdt = '2022/2/1'
edt = '2022/2/28'

startdate = datetime.datetime.strptime(sdt, '%Y/%m/%d')
enddate = datetime.datetime.strptime(edt, '%Y/%m/%d')

dt = startdate
sundaylist = []
while dt < enddate:
    weekday = int(dt.strftime('%w'))
    if (weekday == 0): #Sunday
        sundaylist.append(dt)
    dt += datetime.timedelta(days=1)

stringdates = [ datetime.datetime.strftime(d, '%Y/%m/%d') for d in sundaylist]
print(stringdates)

Output: 50 3010 180610
