I'm using python scripting in blender to create scenes, with static scenes rendered in freestyle. I am aiming to be able to use freestyle style modules (eg japanese_bigbrush.py or user defined) to control freestyle output. I have a function

bpy.context.scene.render.layers["RenderLayer"].use_solid = False
bpy.context.scene.render.layers["RenderLayer"].use_halo = False
bpy.context.scene.render.layers["RenderLayer"].use_zmask = False
bpy.context.scene.render.layers["RenderLayer"].use_all_z = False
bpy.context.scene.render.layers["RenderLayer"].use_ztransp = False
bpy.context.scene.render.layers["RenderLayer"].invert_zmask = False
bpy.context.scene.render.layers["RenderLayer"].use_sky = False
bpy.context.scene.render.layers["RenderLayer"].use_edge_enhance = False
bpy.context.scene.render.layers["RenderLayer"].use_strand = False

bpy.context.scene.render.use_freestyle = True

bpy.context.scene.render.resolution_y = 1500 
bpy.context.scene.render.resolution_x = aspectRatio *1500
bpy.context.scene.render.resolution_percentage =100

#change to script mode
rl = bpy.context.scene.render.layers.active
rl.freestyle_settings.mode = 'SCRIPT'

#add freestyle style module

#open freestyle style module

#render image
bpy.context.scene.render.filepath = PathToRenderedImageHere + fileName + '.jpg'
bpy.ops.render.render( write_still=True )

When calling the freestyle_module_open function I get an error

'expected a string enum in [list of strings eg INVOKE_DEFAULT, INVOKE_REGION_WIN]

I have also tried incorporating the python code from the style module straight into my function. Also adding the style module as a code block in blender. No joy.

I can get it to work if I add the style module manually in blender then run the function, but can't work out how to do this programatically.

You will most likely want to enable freestyle in your render layers settings

bpy.context.scene.render.layers["RenderLayer"].use_freestyle = True

To add a module and set the script you can use -

#open freestyle style module
text_block = bpy.data.texts.load(PathToModuleHere)

#add freestyle style module
freestyle_module = rl.freestyle_settings.modules.new()

#set the script to use
freestyle_module.script = text_block
