# Function to add two numbers
def add(digit1, digit2):
return digit1 + digit2
# Function to subtract two numbers
def subtract(digit1, digit2):
return digit1 - digit2
# Function to multiply two numbers
def multiply(digit1, digit2):
return digit1 * digit2
# Function to divide two numbers
def divide(digit1, digit2):
return digit1 / digit2
print("Please select operation -\n"
"1. Add\n"
"2. Subtract\n"
"3. Multiply\n"
"4. Divide\n")
# Take input from the user
select = input("Select One number for calulator operation form 1, 2, 3, 4 :")
digit1 = int(input("Enter first number: "))
digit2 = int(input("Enter second number: "))
if select == '1':
print(digit1, "+", digit2, "=",
add(digit1, digit2))
elif select == '2':
print(digit1, "-", digit2, "=",
subtract(digit1, digit2))
elif select == '3':
print(digit1, "*", digit2, "=",
multiply(digit1, digit2))
elif select == '4':
print(digit1, "/", digit2, "=",
divide(digit1, digit2))
else:
print("Invalid input")
