With this method static we cant access the object variables, i.e.accessing the rules or the rule number from the class. Either we need this method to be not static as to have access, or we need to pass in the rule number(or any other rule data set we might choose) to be able to compute the next line.

This was given in the outline. `def generate_new_line_from_current_line(prev_line): # Extend the current line two to the left and right. # Want to be able to generate one additional value at each end in the new line. prev_line = '00' + prev_line + '00' new_line = ... return new_line` To compute the new line from the previous line all you need are the switch settings. They are available via `SimEngine.gui_get(<switch number as string>)`. What's not shown is that between constructing `prev_line` and computing `new_line`, you have to generate the sequence of triples derived from the `prev_line`. Each triple, when represented as a string, is a switch name; each such switch gives you an element in the new line. Last edited by rabbott at 21:41 Mar 02, 2020.

def generate_new_line_from_current_line(prev_line):
    # Extend the current line two to the left and right.
    # Want to be able to generate one additional value at each end in the new line.
    prev_line = '00' + prev_line + '00'
    new_line = ...
    return new_line
