I am creating a list of lines and points from text. I want to output directly to line because it is easier than managing the creation of a polyline. I can output as a text fine with start points and end points of line segments, but the conversion from text to line is invalid. What to do?

##################

# Check to see if this file is being executed as the "main" python
# script instead of being used as a module by some other python script
# This allows us to use the module which ever way we want.
if( __name__ == "__main__" ):
    if x:
        CSVlist()

Edit: I have attached the Label and/or Line components to a parameter, for which the representation is null.

Edit2: Solved by bringing a to global scope
