bigframes.pandas.DataFrame.sort_index#

DataFrame.sort_index(*,ascending:bool=True,inplace:Literal[False]=False,na_position:Literal['first','last']='last')→DataFrame[source]#

DataFrame.sort_index(*,ascending:bool=True,inplace:Literal[True]=False,na_position:Literal['first','last']='last')→None

Sort object by labels (along an axis).

Parameters:

• axis ({0 or'index',1 or'columns'},default 0) – The axis along which to sort. The value 0 identifies the rows,and 1 identifies the columns.

• ascending (bool,default True) – Sort ascending vs. descending.

• inplace (bool,default False) – Whether to modify the DataFrame rather than creating a new one.

• na_position ({'first','last'},default 'last') – Puts NaNs at the beginning iffirst;last puts NaNs at the end.Not implemented for MultiIndex.

Returns:

DataFrame with sorted values or None if inplace=True.

Return type:

bigframes.pandas.DataFrame

Raises:

• ValueError – If value ofna_position is not one offirst orlast.

• ValueError – If length ofascending dose not equal length ofby.
