dask.bag.Bag.random_sample
dask.bag.Bag.random_sample¶
- Bag.random_sample(prob, random_state=None)[source]¶
Return elements from bag with probability of
prob.- Parameters
- probfloat
A float between 0 and 1, representing the probability that each element will be returned.
- random_stateint or random.Random, optional
If an integer, will be used to seed a new
random.Randomobject. If provided, results in deterministic sampling.
Examples
>>> import dask.bag as db >>> b = db.from_sequence(range(10)) >>> b.random_sample(0.5, 43).compute() [0, 1, 3, 4, 7, 9] >>> b.random_sample(0.5, 43).compute() [0, 1, 3, 4, 7, 9]
