Subtracting dates to get hours and minutes

[Gronicus at SGA.Ninja]

 As is, Test A works.
 Comment out Test A and uncomment Test B it fails.
 In Test B, I move the data into a variable resulting with the report:
            "TypeError: an integer is required (got type tuple)

How do I fix this?

#-----------------------------------------------------------------------------
import datetime
#=================================================
#         Test A   Hard coded Date/Time
Startt = datetime.datetime(2022, 12, 13,  5,  3, 30) 
Stopp =  datetime.datetime(2022, 12, 12, 21, 15, 30) 

# =================================================
#         Test B   Date/Time data as a variable
#Startt = (2022, 12, 13,  5,  3, 30)
#Stopp =  (2022, 12, 12, 21, 15, 30)

#Startt = datetime.datetime(Startt)
#Stopp =  datetime.datetime(Stopp)

# =================================================
c = Startt - Stopp 
minutes = c.total_seconds() / 60
minutes = c.seconds / 60
hours = 0

while (minutes > 59):
        minutes = minutes - 60
        hours += 1
minutes = round(minutes)
print()
print ("       Hours =  <" + str(hours) + ">")
print ("     Minutes =  <" + str(minutes) + ">")
