I am new to Python and trying to do something I do often in Ruby. Namely, iterating over a set of indices, using them as argument to function and comparing its results with an array of fixture outputs. 

So I wrote it up like I normally do in Ruby, but this resulted in just one test case. 

```
  def test_output(self):
    for i in range(1,11):
      ....
      self.assertEqual(fn(i),output[i])

```

I'm trying to get the test for every item in the range. How can I do that?
