Python –> TypeError: unsupported operand type(s) for -: 'int' and 'str'

Question

HELP, my program is to say what year you are born and then tell you how old you are but I get:

TypeError: unsupported operand type (s) for -: ‘int’ and ‘str’

If someone tells me why or me send the code well done I would appreciate it very much, thanks.

import  datetime
year = int(input("in what year were you born? ---> "))
yearac = datetime.date.today().strftime("%Y")
print(year)
print(yearac)
difere = year - yearac
print("You have",(difere),"years")

Answer 1

strftime (as the name suggests) returns a string, and even though you can cast it to an integer using int like you’re doing with the input, you should use the year attribute instead to get the year as an integer:

 yearac = datetime.date.today().year

Answer 2

use yearac = datetime.date.today().year

Answer 3

It is because yearac is a string. Try int(datetime.date.today().strftime(“%Y”))
