Simple Calculator

Mosh gave me an exercise to create a simple calculator, Ill admit this is not all my own work ( wished I could say it was) Im trying to add a while loop so that I can ask user if they would like to do another calculation.

Here is the code…..

def add(x, y):

return x + y

def subtract(x,y):

return x - y

def devide(x, y):

return x / y

def multiply(x, y):

return x \* y

num1 = float(input("Enter First Number: "))

num2 = float(input("Enter Second Number: "))

print (“select operation.”)

print (“1, Add”)

print (“2, Subtract”)

print (“3, Devide”)

print (“4, Multiply”)

choice = input(“Enter Choice (1/2/3/4):”)

if choice == “1”:

print(num1, "+" ,num2, "=", add(num1,num2))

elif choice == “2”:

print(num1, "-" ,num2, "=", subtract(num1,num2))

elif choice == “3”:

print(num1, "/" ,num2, "=", devide(num1,num2))

elif choice == “4”:

print(num1, "\*" , num2, "=", multiply(num1,num2))

else:

print("invalid option")
