asciigraph | Go package to make lightweight ASCII line graph ╭┈╯ | Chart library

I'm automating the "triangle peg game" found at Cracker Barrel with Python 3.6.0, and I'm currently implementing its graphics with 'turtle'. Two of the classes I've created are relevant to this issue: 'Game' (contained in a module in the main package) and 'TurtleGraphics' (contained in a module in the subpackage 'graphics'), whose intended purposes are self-explanatory. When a 'Game' object is called with a 'TurtleGraphics' object as an argument, the two objects are linked to each other, and 'graphics._construct()' is called, which defines a 'Pen' object and sets its 'stretchfactor' using 'pen()'. Here's where the issue arises. Even though I've set 'resizemode' to 'user' in my 'turtle.cfg' file, I have to set 'resizemode' to 'user' again as an argument to 'pen()' in order for the graphics to construct properly when called from the game. Strangely enough, if I run the module containing 'TurtleGraphics' directly and create a graphics object, it works fine. Also, setting 'stretchfactor' using 'shapesize()' instead of 'pen()' works even when I call the graphics from the game object. First, I'll post the code for 'Game.__call__' and 'TurtleGraphics._construct', prefacing each with the module's imports, which may be relevant. I'll also post 'TurtleGraphics.__init__' and 'TurtleGraphics._draw_board'. (Both classes have base classes, but 'BaseGame' doesn't deal with graphics and 'Graphics' is abstract, so they're irrelevant in this case. Also, it's worth mentioning that 'Game' does not have an '__init__' method. All instance attributes are assigned when it is called.) Then I'll explain the research I've done so far into the matter.
