Your examples are good but I think they can be more simpler

Initialize an unordered_set;
Loop through the array and in each iteration, insert abs(i) into the unordered_set.

Time complexity
O(n)
Insertions into unordered_set cost O(1) so all that we worry about is the length of the array n and the cost of loop through O(n).

Hey! I'm really happy with all your examples! But, I must say sometimes your code in python sometimes need to be more python. I mean there are some internal functions that can help to do it faster, better and cleaner, take a look to this one:

def solution(A):
A = [abs(ele) for ele in A]
A.sort()
return len(set(A))
