What is the best way (best as in the conventional way) of checking whether all elements in a list are unique?
My current approach using a
>>> x = [1, 1, 1, 2, 3, 4, 5, 6, 2] >>> counter = Counter(x) >>> for values in counter.itervalues(): if values > 1: # do something
Can I do better?
Now we will see solution for issue: Checking if all elements in a list are unique
Not the most efficient, but straight forward and concise:
if len(x) > len(set(x)): pass # do something
Probably won’t make much of a difference for short lists.
