| 64 | A class used to check the whether the actual output from a doctest |
| 65 | example matches the expected output. <tt class="class">OutputChecker</tt> |
| 66 | defines two methods: <tt class="method">check_output</tt>, which compares a given |
| 67 | pair of outputs, and returns true if they match; and |
| 68 | <tt class="method">output_difference</tt>, which returns a string describing the |
| 69 | differences between two outputs. |
