In an email, I received this question as part of a newsletter. def fetch_squares ( max_root ): squares = [] for x in range ( max_root ): squares . append (x **2) return squares
MAX = 5 for square in fetch_squares (MAX ): do_something_with ( square ) 1) Do you see a memory bottleneck here? If so, what is it? 2) Can you think of a way to fix the memory bottleneck? Want to know if I am trying to solve the correct bottleneck. I am thinking that the bottleneck is to create a list only to iterate the same list you created sort of doubling the time through. Is that the correct problem to solve? If it is then I thought the best way is just to supply the numbers on the fly, a generator. def supply_squares(max_root): for x in max_root: yield x MAX = 5 So then I set up a loop and do whatever is needed. At this time I am creating generator objects. But is this the correct way to go? More of a am I thinking correctly questino. item = 0 while item < MAX: print(supply_squares(item)) item += 1 <generator object supply_squares at 0x0000000004DEAC00> <generator object supply_squares at 0x0000000004DEAC00> <generator object supply_squares at 0x0000000004DEAC00> <generator object supply_squares at 0x0000000004DEAC00> <generator object supply_squares at 0x0000000004DEAC00> Thanks Sayth -- https://mail.python.org/mailman/listinfo/python-list
