@astaric, similar code warnings are stupid. See this -- codeclimate complained about two totally different lists of error in |
| empty_data = Msg("Empty data set") | ||
| mahalanobis_error = Msg("{}") | ||
| distances_memory_error = Msg("Not enough memory.") | ||
| distances_value_error = Msg("Error occurred while calculating distances: {}") |

The error can be long, so "Error occurred while calculating distances\n{}". Skip the colon, so the error looks OK, and the tooltip shows the entire message.

A stylistic comment. I don't like the obvious radon fixes --- here's a code that's too complex so let's tear out a chunk of it into a separate function.
The main job of compute_distances is not to run various checks and fixes, and in the end, yes, call a local function that computes distances.
Turn it around. The "auxiliary" code should be the code that prepares the data and not the code that does the work. So, factor out the preprocessing/checking instead.

Use side_effect as a keyword argument for mock. I wouldn't even bother to have a mock variable here; I'd use Mock(side_effect=ValueError) as an argument.
