So, I have my code here:import turtleclass fractal:    A class containing methods that will replicate    various fractals.    Attributes:        num: An integer representing the number of iterations        t: A turtle graphics object imported from Turtle.py        def __init__(self, num, t=turtle.Turtle()):        self.num = num        self.t = t    def kochCurve(self):        axiom = 'F'        for _ in range(self.num):            linSys = 'F+F--F+F'            axiom = axiom.replace('F',linSys)        for i in axiom:            if i == 'F':                self.t.forward(10)            elif i == '+':                self.t.left(60)            elif i == '-':                self.t.right(60)    def kochIsland(self):        axiom = 'F-F-F-F'        for _ in range(self.num):            linSys = 'F+FF-FF-F-F+F+F'            axiom = axiom.replace('F',linSys)        for i in axiom:            if i == 'F':                self.t.forward(10)            elif i == '+':                self.t.left(90)            elif i == '-':                self.t.right(90)    def tree(self):        axiom = '[X]'        for _ in range(self.num):            linSys = 'F-[[X]+X]+F[+FX]-X'            axiom = axiom.replace('X',linSys)            axiom = axiom.replace('F','FF')        self.t.setheading(90)        self.t.setposition(0,-300)        stack = []        for i in axiom:            if i == 'F':                self.t.forward(10)            elif i == '+':                self.t.right(25)            elif i == '-':                self.t.left(25)            elif i == '[':                pos = self.t.position()                head = self.t.heading()                stack.append((pos,head))            elif i == ']':                (pos,head) = stack.pop()                self.t.penup()                self.t.setposition(pos)                self.t.setheading(head)                self.t.pendown()fractal(3).kochCurve()Overall, the code just seems a bit redundant and LONG. I'm creating this class to share on a repository for some others to view. However, I don't particularly enjoy the way it looks.Essentially, this class makes a turtle from Turtle Graphics and draws fractals with it. So far, I have the three different fractals. All that's needed to call into the object is an integer that will be the number of iterations. What improvements can I make here?
