dask.bag.from_sequence(seq, partition_size=None, npartitions=None)[source]

Create a dask Bag from Python sequence.

This sequence should be relatively small in memory. Dask Bag works best when it handles loading your data itself. Commonly we load a sequence of filenames into a Bag and then use .map to open them.

seq: Iterable

A sequence of elements to put into the dask

partition_size: int (optional)

The length of each partition

npartitions: int (optional)

The number of desired partitions

It is best to provide either ``partition_size`` or ``npartitions``
(though not both.)
