python is there a built in way to return a list generator instead of list from random.sample

I use random.sample to sample from a very large range depending on the input load. Sometimes the sample itself is very large and since it is a list it occupies a lot of memory.

The application does not necessarily use all the value in the list. It would be great if random.sample can return a list generator instead of a list itself.

Right now I have a wrapper that divides the large input range into equal sized buckets and use randint to select a random number from each n / sample_size buckets.
