pandas 1.4.2

ParametersReturns
_slice_take_blocks_ax0(self, slice_or_indexer: 'slice | np.ndarray', fill_value=<no_default>, only_slice: 'bool' = False, *, use_na_proxy: 'bool' = False) -> 'list[Block]'

Overloaded for SingleBlock

Parameters

slice_or_indexer : slice or np.ndarray[int64]
fill_value : scalar, default lib.no_default
only_slice : bool, default False

If True, we always return views on existing arrays, never copies. This is used when called from ops.blockwise.operate_blockwise.

use_na_proxy : bool, default False

Whether to use a np.void ndarray for newly introduced columns.

Returns

new_blocks : list of Block

Slice/take blocks along axis=0.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
