Calculator Program in Python
Simple Calculator Program in Python
This example helps to learn how to create a simple calculator program to perform operations like addition, subtraction, multiplication, and division.
Source Code
The following is the source code to perform simple calculations. In this program, we will perform addition, subtraction, multiplication, and division operations.
Function to perform addition operation
def addition(num1, num2):
return num1 + number2
Function to perform subtraction operation
def subtraction(num1, num2):
return num1 — num2
Function to perform multiplication operation
def multiplication(num1, num2):
return num1 * num2
Function to perform division operation
def division(num1, num2):
return num1 / num2
Choose operation
print(“Select desired operation: \n”
“1.Add\n”
“2.Substraction\n”
“3.Multiplication\n”
“4.Division”)
while True:
# Take input from the user
operation = input(“Choose operation(1/2/3/4): “)
# Check if operation is one of the four options if operation in (‘1’, ‘2’, ‘3’, ‘4’):
number1 = float(input(“Enter first number: “))
number2 = float(input(“Enter second number: “))
if operation == ‘1’:
#Print sum of two number
print(number1, “+”, number2, “=”, addition(number1, number2))
elif operation == ‘2’:
# Print subtraction of two number
print(number1, “-”, number2, “=”, subtraction(number1, number2))
elif operation == ‘3’:
# Print multiplication of two number
print(number1, “*”, number2, “=”, multiplication(number1, number2))
elif operation == ‘4’:
# Print division of two number
print(number1, “/”, number2, “=”, division(number1, number2))
break else:
print(“Wrong operation selected”)
