简化类似功能的Python Turtle绘图

Question

有没有办法简化这个功能，就if语句少而反复输入相同的代码？

此函数根据用户请求的数字创建正弦图。有很多重复的代码。我尝试使用列表来存储对象，但在尝试访问它们时会出错。我该如何解决这个问题？

 def createWaves(amp, count):
            even_num = [2, 4, 6, 8, 10, 12]
            alpha = createTurtle("turtle", "darkcyan", 2)
            alpha.ht()
            beta = createTurtle("turtle", "purple", 2)
            beta.ht()
            gamma = createTurtle("turtle", "orange", 2)
            gamma.ht()
            delta = createTurtle("turtle", "magenta", 2)
            delta.ht()
            epsilon = createTurtle("turtle", "deepskyblue", 2)
            epsilon.ht()
            zeta = createTurtle("turtle", "green", 2)
            zeta.ht()
            omega = createTurtle("turtle", "black", 3)
            omega.ht()
            if count == 0:
                alpha.st()
                for x in range(361):
                    y_alpha = (amp/even_num[0]) *(math.sin(math.radians(x*even_num[0])))
                    alpha.goto(x, y_alpha)
            elif count == 1:
                alpha.st()
