Please is anything wrong with this code?

Question

elif user_input == "add":
num1 = float(input("Enter a number: "))
num2 = float(input("Enter another number: "))
result = str(num1 + num2)
print("The answer is " + result)

Answer 1

If this is a part of a code then it's right but if it's a standalone code then it's a faulty code

Answer 2

Yeah, it's part of a main code trend...
