Nice! Is there an advantage in using a set comprehension over set(a) or is it just a stylistic choice?

- ghshephard 12y agoNone that I know of - As a novice python programmer, I just try and use comprehensions for everything so my eyes get used to the pattern. The set function is somewhat faster. a=[] for x in range(10000): a.append(randint(1,2000)) %timeit b=set(a) 1000 loops, best of 3: 373 µs per loop %timeit b={x for x in a} 1000 loops, best of 3: 542 µs per loop

- michaelmior 12y agoWhile comprehensions are definitely standard Python, I would argue that if you're not actually changing any value (as is the case here, then just `set(a)`, being much simpler, is more Pythonic.
