Writing Functions that Return a Value in Python

 
# Input: Interactive

 

# Output: Result of arithmetic operation

 

# Write performOperation function here

 

def performOperation(a, b, op):

 

    """ This function returns value after performing operation op on a and b """

 

    if op == '+':

 

        return a + b

 

    elif op == '-':

 

        return a - b

 

    elif op == '*':

 

        return a * b

 

    elif op == '/':

 

        return a / b;

 

if __name__ == '__main__':

 

    numberOne = int(input("Enter the first number: "))

 

    numberTwo = int(input("Enter the second number: "))

 

    operation = input("Enter an operator (+ - * /): ")

 

    # Call performOperation method here and store the value in "result"

 

    result = performOperation(numberOne, numberTwo, operation)

 

    print(str(numberOne) + " " + operation + " " + str(numberTwo) + " = " + str(result))
