Whats wrong with this calculator?

Question

# Created by matrix

def add(x, y):
return x + y

def subtract(x, y):
return x - y

def multiply(x, y):
return x * y

def divide(x, y):
return x / y

print("select opration")
print("1. Add")
print("2. Subtract")
print("3. Multiply")
print("4. Divide")

while True:
choice = input("enter choice(1/2/3/4)")
if choice in("1","2","3","4"):
num1 = float(input("enter first number: "))
num2 = float(input("enter second number: "))
if choice == "1":
print("num1", "+", "num2", "=", add(num1, num2))
elif choice == "2":
print("num1", "-", "num2", "=", subtract(num1, num2))
elif choice == "3":
print("num1", "*", "num2", "=", multiply(num1, num2))
elif choice == "4":
print("num1", "/", "num2", "=", divide(num1, num2))

else:
print("invalid input")
elif choice=="Exit":
break
else:
print("invalid input")

Answer 1

I fixed your code!
you need to select choice,inputs before entering into the loop and u need to use break for every condition to break the action after specific operation....only this was the error in your code:)

Answer 2

It seems to be working fine for me. What did you use for input? You most likely just got that error because it's expecting more input since it's looping with the while True unless you type Exit.
