## So this is my first python program

### calculator


def add():
    result = first_no + second_no
    print(result)

def mul():
    result = first_no * second_no
    print(result)

def div():
    pass

def sub():
    pass


if __name__ == '__main__':
    first_no = 10
    second_no = 20

    # call addition
    add()
    mul()
