Examples

Let’s begin by importing vastorbit.

import vastorbit as vo

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

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

Let’s extract the first 3 characters of name.

data["name"].str_slice(start = 1, step = 3)

	Abc name Varchar(19)
1	Mr
2	Mr
3	Mr
4	Dr

Rows: 1-4 | Column: name | Type: varchar(19)
