I would like to give some feedback about ...
I was trying to check the solution which i think works but the system does not recognize it - it keeps comparing my solution to solution with alternative initial list every time i press "check" so that they never match... please advise
Solution:
nums = [1,2,2,3,3,4,6,6,6,7,8,5,9]
Xnums = [x for x in nums if nums.count(x)>1]
