Only two. 1.) I was impressed by their clarity and conciseness when I first discovered them. 2.) I also read now and then that simple list comprehensions are faster when compared with their for-loop equivalents because of the way comprehensions are implemented under the hood. My example is a far cry from a "simple" comprehension, however. :) > If there's only one call to func(), and you ignore the (probably) fixed > cost of jumping into a generator each time, then it shouldn't make any > difference. > > If you are comparing one call to func() in a for loop versus three calls > to func() in a list comp or generator expression, then of course the for > loop will be more efficient. I agree. I would rather call func() only once per iteration in any case. I will revise it to a plain for loop with a single call.
