verticapy.vDataFrame.swap#
- vDataFrame.swap(column1: int | str, column2: int | str) vDataFrame #
Swap the two input vDataColumns.
Parameters#
- column1: str | int
The first vDataColumn or its index to swap.
- column2: str | int
The second vDataColumn or its index to swap.
Returns#
- vDataFrame
self
Examples#
Let’s begin by importing VerticaPy.
import verticapy as vp
Hint
By assigning an alias to
verticapy
, we mitigate the risk of code collisions with other libraries. This precaution is necessary because verticapy uses commonly known function names like “average” and “median”, which can potentially lead to naming conflicts. The use of an alias ensures that the functions fromverticapy
are used as intended without interfering with functions from other libraries.Let us create a dummy dataset and swap its columns:
vdf = vp.vDataFrame( { "val" : [0, 10, 20], "cat": ['a', 'b', 'c'], }, )
123valInteger100%AbccatVarchar(1)100%1 0 a 2 10 b 3 20 c We can swap the categorical column and value columns:
vdf.swap("val", "cat")
