Hello, been working on automating some HDAs parameters creation using the following python script:

import hou 

def python_module_script():
    pythonScript1 = 'def onCreated(node):\n    node.setColor(hou.Color((0.0, 0.0, 0.0)))\n    node.setUserData("nodeshape", "diamond")'
    pythonScript2 = 'kwargs["node"].hdaModule().onCreated(kwargs["node"]);'
    return pythonScript1, pythonScript2


hda_node = subnet.createDigitalAsset(
    name=hda_name,
    hda_file_name=hdalib_dic + hda_name + ".hda",
    description=hda_name,
    min_num_inputs=0,
    max_num_inputs=0,
    install_path=hdalib_dic,
    ignore_external_references=True,
    create_backup=True,
)

hda_node.setName(hda_name)
hda_def = hda_node.type().definition()

scriptPM, scriptOC = python_module_scripts()

hda_def.addSection("PythonModule", str(scriptPM))
hda_def.addSection("OnCreated", str(scriptOC))

What I want to include is to make sure the scripting language on the Edit Operator Type Properties menu > scripts > Edit as dropdown changes from Hscript to Python, does anybody know how to do that?

Solved it, just needed to include: 
setExtraFileOption(name, value, type_hint = hou.fieldType::NoSuchField)
as seen on the documentation.

So now it's just: 
hda_def.addSection("PythonModule", str(scriptPA))
hda_def.setExtraFileOption('PythonModule/IsPython', True)
hda_def.addSection("OnCreated", str(scriptOC))
hda_def.setExtraFileOption('OnCreated/IsPython', True)
