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
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.
