- Help on method sample in module random:
- sample(population, k) method of random.Random instance
- Chooses k unique random elements from a population sequence or set.
-
- Returns a new list containing elements from the population while
- leaving the original population unchanged. The resulting list is
- in selection order so that all sub-slices will also be valid random
- samples. This allows raffle winners (the sample) to be partitioned
- into grand prize and second place winners (the subslices).
-
- Members of the population need not be hashable or unique. If the
- population contains repeats, then each occurrence is a possible
- selection in the sample.
-
- To choose a sample in a range of integers, use range as an argument.
- This is especially fast and space efficient for sampling from a
- large population: sample(range(10000000), 60)
