# Python program for simple calculator 

def add(num1, num2): 
    # Function to add two numbers 
	return num1 + num2 

def subtract(num1, num2): 
	return num1 - num2 

def multiply(num1, num2): 
	# Function to multiply two numbers 
	return num1 * num2 

def divide(num1, num2): 
	# Function to divide two numbers 
	return num1 / num2 

print("Please select operation -\n" \ 
		"1. Add\n" \ 
		"2. Subtract\n" \ 
		"3. Multiply\n" \ 
		"4. Divide\n") 


# Take input from the user 
select = int(input("Select operations form 1, 2, 3, 4 :")) 

number_1 = int(input("Enter first number: ")) 
number_2 = int(input("Enter second number: ")) 

if select == 1: 
	print(number_1, "+", number_2, "=", 
					add(number_1, number_2)) 

elif select == 2: 
	print(number_1, "-", number_2, "=", 
					subtract(number_1, number_2)) 

elif select == 3: 
	print(number_1, "*", number_2, "=", 
					multiply(number_1, number_2)) 

elif select == 4: 
	print(number_1, "/", number_2, "=", 
					divide(number_1, number_2)) 
else: 
	print("Invalid input") 

Output :

Please select operation -
1. Add
2. Subtract
3. Multiply
4. Divide
Select operations form 1, 2, 3, 4 : 1
Enter first number : 15
Enter second number : 14
15 + 14 = 29
