Adding Value list using python code

Hi I’m trying to write a code that adds or removes a input into the python scripting component and then add ValueList component to a specified input of the ghpython component. I’ve got the adding and removing of the inputs figured out but I’m having issue with the value list section of the code. If anyone can assist me with what I might be doing wrong, it’s greatly appreciated. Code and file attached below
