verticapy.vDataColumn.str_replace#

vDataColumn.str_replace(to_replace: str, value: str | None = None) → vDataFrame#

Replaces the regular expression matches in each of the vDataColumn record by an input value. The vDataColumn will be transformed.

Parameters#

to_replace: str: Regular expression to replace.
value: str, optional: New value.

Returns#

vDataFrame: self._parent

Examples#

Let’s begin by importing VerticaPy.

import verticapy as vp

Let’s generate a small dataset using the following data:

data = vp.vDataFrame(
    {
        "name": [
            'Mr. Steve Smith',
            'Mr. Charlie Dickens',
            'Mrs. Helen Ross',
            'Dr. Jack Smith',
        ]
    }
)

Let’s replace the name prefix with static text “[Name_Prefix]”.

data["name"].str_replace(
    to_replace  = "([A-Za-z])+\.",
    value = "[Name_Prefix]"
)

	Abc name Varchar(391) 100%
1	[Name_Prefix] Steve Smith
2	[Name_Prefix] Charlie Dickens
3	[Name_Prefix] Helen Ross
4	[Name_Prefix] Jack Smith
