dask.dataframe.DataFrame.partitions¶
- property DataFrame.partitions¶
Slice dataframe by partitions
This allows partitionwise slicing of a Dask Dataframe. You can perform normal Numpy-style slicing, but now rather than slice elements of the array you slice along partitions so, for example,
df.partitions[:5]produces a new Dask Dataframe of the first five partitions. Valid indexers are integers, sequences of integers, slices, or boolean masks.- Returns
- A Dask DataFrame
Examples
>>> df.partitions[0] >>> df.partitions[:3] >>> df.partitions[::10]
