how to make a calculator using python code example
Example 1: simple python calculator
num1 = input('Enter first number: ')
num2 = input('Enter second number: ')
sum = float(num1) + float(num2)
sum2 = float(num1) - float(num2)
sum3 = float(num1) * float(num2)
sum4 = float(num1) / float(num2)
choice = input('Enter an operator, + = addition, - = subtraction, * = multiplication and / = division: ')
if choice == '+':
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))
if choice == '-':
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum2))
if choice == '*':
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum3))
if choice == '/':
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum4))
Example 2: calculator in python
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
op = input("Enter operator: ")
def add(num1, num2):
print('Result: ', num1 + num2)
def subtract(num1, num2):
print('Result: ', num1 - num2)
def multiply(num1, num2):
print('Result: ', num1 * num2)
def division(num1, num2):
print('Result: ', num1 / num2)
if op == '+':
add(num1=num1, num2=num2)
elif op == '-':
subtract(num1=num1, num2=num2)
elif op == '*':
multiply(num1=num1, num2=num2)
elif op == '/':
division(num1=num1, num2=num2)
else:
print('Invalid operator')
Example 3: how to make a calculator in python
def add(num1, num2):
return num1 + num2
def subtract(num1, num2):
return num1 - num2
def multiply(num1, num2):
return num1 * num2
def divide(num1, num2):
return num1 / num2
