Cut Column

This transform will slice each string value in a specific column based on the index numbers. This is applicable only for string columns in a dataset.

Parameters

The table gives a brief description about each parameter in Cut Column transform.

Name:

By default, the transform name is populated. You can also add a custom name for the transform.

Input Dataset:

The file name of the input dataset. You can select the dataset that was uploaded from the drop-down list. (Required: True, Multiple: False)

Output Dataset:

The file name with which the output dataset is created after slicing each string value based on the given index range from the input dataset. (Required: True, Multiple: False)

Column:

The column name on which the cut column transform must be performed. (Required: True, Multiple: True, Datatypes: [“STRING”], Options: [‘FIELDS’], Datasets: [‘df’])

First character index:

The index value of the first character from which the slicing should happen. (Required: True, Multiple: False, Datatypes: [‘LONG’], Options: [‘CONSTANT’])

:Last character index : The index value of the last character up to which the slicing should happen and return the range of characters or part of string. (Required: True, Multiple: False, Datatypes: [‘LONG’], Options: [‘CONSTANT’])

How to use it in Notebook

The following is the code snippet you must use in the Jupyter Notebook editor to run the Cut Column transform:

template=TemplateV2.get_template_by('Cut Column')

recipe_Cut_Column= project.addRecipe([car_data, employee_data, temperature_data, only_numeric], name='Cut Column')

transform=Transform()
transform.templateId = template.id
transform.name='Cut Column'
transform.variables = {
'input_dataset':'car',
'output_dataset':'car_cutted',
'col':"CarName",
'i':0,
'j':4}
recipe_Cut_Column.add_transform(transform)
recipe_Cut_Column.run()
