4.  Define a Python function check_two_zeroes (a, b, c) with three int arguments a, b, c. When called passing specific values for a, b, and c, your function should return True when exactly two of the three arguments a, b, c are equal to zero.  Otherwise, your function should return False. For example, check_sum (0,1,0) should return True, since  a == 0 and c == 0, but b != 0.  check_product (0,0,0) should return False, since all three are == 0.
