What's the error?

Question

print ("Wanna know ideal age of gf?")
Your_age = input("Put your age : ")
Your_fav_number = (4)
print ("Ideal age of your gf is" + str (Your_age + Your_fav_number ) )

Answer 1

input() return string, that mean Your_age value is string, but you try to add it with int at the last line. Thats why
Convert the input to int, it should work

Answer 2

int(input("somethinh"))

Answer 3

can you edit it and give it to me?
