The input function returns the string value. So you need to convert it to
number before the math you do.
birth_year = input("What year are you born? ")
current_year = 2019
print(type(birth_year))
age = current_year - int(birth_year)
print(age)
—————
python3 age.py
What year are you born? 1989
<class 'str'>
