inputs = {

}
params = {
    "inputs": inputs,
    "b_output_action": True,
    "outer_pipeline_stages": None,
    "input_column_str": "",  # @param {"label":"input_column_str","type":"string","required":"true","helpTip":""}
    "output_column_str": "",  # @param {"label":"output_column_str","type":"string","required":"true","helpTip":""}
    "handle_invalid": "keep"  # @param {"label":"handle_invalid","type":"enum","options":"skip,error,keep","required":"true","helpTip":""}
}
string_indexer____id___ = MLSStringIndexer(**params)
string_indexer____id___.run()
# @output {"label":"dataframe","name":"string_indexer____id___.get_outputs()['output_port_1']","type":"DataFrame"}
