just add the python code block. FArekkusu is too lazy to do it himself...

From the description:

Contrary to the example below, the output in Python should be a tuple of 4 lists instead of a 2-dimensional list

there are code blocks specifically built for this. Use them...

Added a note in the description.

@FArekkusu: you forgot to update the description (output type in python is different from the JS one)

The example in python suggest list of lists to be returned. Test case expecting tuple. There should be consistency. Just wasted few mintes to figure this out.
