concat_blocks

Note

This page is a reference documentation. It only explains the function signature, and not how to use it. Please refer to the Habitat Guide and Python API guide (v2.0) for usage.

concat_blocks(blocks: Sequence[DataFrame], *, owner: str) → DataFrame[source]

Concatenate child blocks column-wise with a duplicate-column guard.

Parameters:

  • blocks – Child blocks in child order.

  • owner – Combiner name used in error messages.

Returns:

The merged block. A single child is returned as a copy, so a combiner node with one child behaves as a transparent rename point.

Raises:

HABITAPIError – On row mismatch or duplicated output column names.
