 @victormoron are the fixes to the docstrings failing because of the PR10 error? The fixes are correct, but seem unrelated. In general try to keep one PR per concept, if PR10 can already be validated, would be better to have it in a separate PR. If they are related, I think the validation is not working as expected. @datapythonista. Basically the problem was not related with the fact of the space after the variable name, was related with the type not being defined. I firstly tried to delete the colon as suggested in the documentation, but then error was raised as type was required. I finally added the type of variable to get rid of the colon space problem. Hope that answers the question.

Should I update your suggestions and do another PR?  Looks like the validation script reported PR10 for some false positives then, I wasn't aware. That would belong to another PR, if you can address the comments, happy to get this merged. @datapythonista  should be ok now. let me know thanks @victormoron
