PYTHON BEGINNERS - 16 : BETTER CALCULATOR

 IN THIS TUTORIAL, WE WILL BUILT 4 FUNCTIONAL CALCULATOR:

num1 = float(input("Enter first number: "))

op = input("Enter operator: ")

num2 = float(input("Enter second number: "))

if op == "+":

    print(num1 + num2)

elif op == "-":

    print(num1 - num2)

elif op == "/":

    print(num1/num2)

elif op == "*":

    print(num1 * num2)

else:

    print("invalid operator")
