subtracting two times in python

Question

I have a problem with my code. I am trying to subtracting the two times but it give me an error:

TypeError: unsupported operand type(s) for -: 'time.struct_time' and 'time.struct_time'

The error are jumping on this line:

diff = (end_dt - start_dt)

When I try this:

start = "09:35:23"
end = "10:23:00"
start_dt = time.strptime(start, '%H:%M:%S')
end_dt = time.strptime(end, '%H:%M:%S')
diff = (end_dt - start_dt)

Can you please help me how to fix the error that I am getting?

Answer 1

You need to use the datetime module:

import datetime

start = "09:35:23"
end = "10:23:00"
start_dt = datetime.datetime.strptime(start, '%H:%M:%S')
end_dt = datetime.datetime.strptime(end, '%H:%M:%S')
diff = (end_dt - start_dt)
print(diff)

Output

datetime.timedelta(0, 2857)

This generates two datetime objects, start_dt and end_dt . When you subtract one from the other it returns a timedelta .
