Subtracting dates to get hours and minutes

[Gronicus at SGA.Ninja]

I realized it had something to do with tupilation
The simple fix is to add the * into the original code.
Startt = datetime.datetime(*Startt)

I am not sure what "dts1 == Startt  # True" does....

Thank you.....

Your problem is that datetime.datetime does not accept a tuple as an
argument.  It expects an integer value for the first argument, but you
supplied a tuple.  In Python, you can use a sequence (e.g., tuple or
list) the way you want by prefixing it with an asterisk.  This causes the
sequence of items to be treated as individual arguments. So:

Startt = datetime.datetime(2022, 12, 13,  5,  3, 30)
st1 = (2022, 12, 13,  5,  3, 30)
dts1 = datetime.datetime(*st1)  # NOT datetime.datetime(st1)
dts1 == Startt  # True
