Question: 
Write a python function to count the number of equal numbers from three given integers.


Model's Code:
def test_three_equal(a, b, c):
    return len(set([a, b, c]))  # Count of unique numbers in the set



Sample Correct Code:
def test_three_equal(x,y,z):
  result= set([x,y,z])
  if len(result)==3:
    return 0
  else:
    return (4-len(result))


Asserts:
assert test_three_equal(1,1,1) == 3
assert test_three_equal(-1,-2,-3) == 0
assert test_three_equal(1,2,2) == 2


Tests:
Test 1 of 3: FAIL: AssertionError()
