PYTHON CALCULATOR code example

Example 1: python calculator

print("Enter Your Choice 1(Add)/2(Sub)/3(Divide)/4(Multiply)")
num = int(input())
if num == 1:
    print("Enter Number 1 : ")
    add1  = int(input())

    print("The Difference Is ", difference)
elif num == 3:
    print("Enter Number 1 : ")
    div1  = float(input())
    print("Enter Number 2 : ")
    div2 = float(input())
    division = div1 / div2
    print("The Division Is ", division)
elif num == 4:
    print("Enter Number 1 : ")
    mul1 = int(input())
    print("Enter Number 2 : ")
    mul2 = int(input())
    multiply = mul1 * mul2
    print("The Difference Is ", multiply)
else:
    print("enter a valid Number")

Example 2: python calculator

num_one = int(input("Enter 1st number: "))

op = input("Enter operator: ")

num_two = int(input("Enter 2nd number: "))

if op == "+":
    print(num_one + num_two)
elif op == "-":

elif op == "*" or op == "x":
    print(num_one * num_two)
elif op == "/":
    print(num_one / num_two)
