Usage Details

runScript(inputTable, scriptName, entryFunction, explodeFields)

Input:
inputTable: Table containing the data to run this operator on.
scriptName: Name of the Python script that contains the function.
entryFunction: The function to be executed for each row. Use parent column names as function arguments.
explodeFields: Whether to explode the output fields (true) or not (false).

output:
entryFunction runs on each row of the parent table.
if explodeFields is false, the results of entryFunction appear in a result column.
if explodeFields is true, entryFunction returns a dictionary. The keys of dictionary become columns of the output table.
if explodeFields is true and entryFunction returns something other than the dictionary, the result is shown in the other_field column.

Examples

script

from lhub_integ import action

# Functions annotated with @action can be called in runScript automation
# Try using the actions defined below by mapping columns to the parameters and hit Run

@action
def sum_and_product(column1, column2):
	# Return a dictionary to create multiple columns in the output table with explode set true
	# If explode is set to false, you will get the dictionary as json in `result` column
	return { "sum" : column1 + column2, "product" : column1 * column2 };

@action
def double(column1):
	# Return a non-dictionary type to get the value in an `other_field` column
  return column1 * 2;
