Definition: isString(fieldname: str) → bool
Description: Checks if a specific field is of type, string. The return value can be further used to transform your data. For example, converting the string to a number.
Parameters: fieldname: The name of the field whose value is to be checked.
Returns: -  True, if the specified field’s value is of type, string.
-  False, for null and other data type values.

The following script checks if the specified property is a string:

from io.hevo.api import Event

def transform(event):
    <existing_properties> = event.getProperties()

    <boolean_value_type> = event.isString('<property_name>')

    return event

Sample Transformation

The following script checks if the routing_number property is a string. The isString property displays the return value of the method:

from io.hevo.api import Event

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

    # Set a property to the return value of the method
    properties['isString'] = event.isString('routing_number')

    return event

Sample Output

The Transformation sets the isString property to true, as the routing_number is a string.
