meerkat.ops.concat module#

concat(objs: Sequence[DataPanel] | Sequence[AbstractColumn], axis: str | int = 'rows', suffixes: Tuple[str] = None, overwrite: bool = False) → DataPanel | AbstractColumn[source]#

Concatenate a sequence of columns or a sequence of DataPanel`s. If sequence is empty, returns an empty `DataPanel.

  • If concatenating columns, all columns must be of the same type (e.g. all

ListColumn). - If concatenating `DataPanel`s along axis 0 (rows), all `DataPanel`s must have the same set of columns. - If concatenating `DataPanel`s along axis 1 (columns), all `DataPanel`s must have the same length and cannot have any of the same column names.

Parameters:

  • objs (Union[Sequence[DataPanel], Sequence[AbstractColumn]]) – sequence of columns or DataPanels.

  • axis (Union[str, int]) – The axis along which to concatenate. Ignored if concatenating columns.

Returns:

concatenated DataPanel or column

Return type:

Union[DataPanel, AbstractColumn]
