Python Beginner: Building a Better Calculator

 Hello, developer!

Hope you are having confidence on Python programming! You can get input from user, printing out results with your data type, making lists & tuples, building functions and using if statements.

Today, we will build up a upgraded calculator. It supports add, subtract, multiplying and division of 2 input numbers.

I showed the better calculator codes and execution result as following.

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")

Can you see the same result on your PC? Great job! I recommend you have some time to improve this calculator with more useful calculation features.

See you on the next post, developer! 😊
