day #6 - Exercise 1: make two Calculator using in python

 I have two calculator programs code :

You can easily use it on computer and mobile:-

Our 1st.Question--

Create a calculator capable of performing addition , subtraction, multiplication and division operations 

on two numbers.

Our program code--

Input-

a=int(input("enter your first number:"))

b=int(input("enter your second number:"))

print(a+b)

print(a-b)

print(a*b)

print(a/b)

Output-

enter your first number:5

enter your second number:5

10

0

25

1.0

Our 2nd Question.:

how to make best & advance calculator to include anything.?

Our program code:

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):

    if y == 0:

        return "Error! Division by zero!"

    else:

        return x / y

print("Select operation:")

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("Result:", add(num1, num2))

        elif choice == '2':

            print("Result:", subtract(num1, num2))

        elif choice == '3':

            print("Result:", multiply(num1, num2))

        elif choice == '4':

            print("Result:", divide(num1, num2))

    else:

        print("Invalid Input")

    next_calculation = input("Do you want to perform another calculation? (yes/no): ")

    if next_calculation.lower() != 'yes':

        break

Output-
