Python new test framework

c# version i have a error.
my code runned correctly in visual studio.

int[]' does not contain a definition for 'GroupBy' and no accessible extension method 'GroupBy' accepting a first argument of type 'int[]' could be found (are you missing a using directive or an assembly reference?)

what am I missing ?

Hope that's the first one of many :D

Thank you. :) My first translation ever! xD
