Retrieve the Type for a Value

The following script takes the value of the variable in the <someNumber> field and utilizes the getType function to determine its data type. It assigns the returned type as a string to the new field, <type>.

These data types can be helpful to assess any necessary modifications to the raw data.

Note: Replace the placeholder values in the script with your own.

from io.hevo.api import Event
from io.hevo.api import Utils

def transform(event):
    eventName = event.getEventName()
    properties = event.getProperties()

    <someNumber> = <value of the variable>
    properties['type'] = Utils.getType(<someNumber>)
        ...

Sample Transformation

Consider the following two fields:

• address - contains street, state, and country details
• id - contains identification details

The gettype function extracts the data types of the id and address fields and stores them in the id_type and address_type fields, respectively.

from io.hevo.api import Event
from io.hevo.api import Utils


def transform(event):
    properties = event.getProperties()

    id_type = Utils.getType(properties['id'])
    properties['id_type'] = id_type

    address_type = Utils.getType(properties['address'])
    properties['address_type'] = address_type

    return event

Sample Output

The id_type and address_type fields are created and the data types of the id and address fields are stored in these, respectively.
