运用turtle实现一个简易计算器程序

好的，以下是一个简单的turtle计算器程序：

import turtle

# 初始化turtle窗口
turtle.setup(width=600, height=400)
turtle.title("Calculator")

# 定义画布和画笔
canvas = turtle.Screen()
pen = turtle.Turtle()
pen.penup()

# 定义计算器的状态变量
operator = ""
num1 = ""
num2 = ""
result = ""

# 定义数字按钮的点击事件
def onButtonClick(num):
    global operator, num1, num2, result
    if operator == "":
        num1 += str(num)
        pen.goto(-200, 0)
        pen.write(num1, font=("Arial", 24, "normal"))
    else:
        num2 += str(num)
        pen.goto(0, 0)
        pen.write(num2, font=("Arial", 24, "normal"))

# 定义运算符按钮的点击事件
def onOperatorClick(op):
    global operator, num1, num2, result
    operator = op
    pen.goto(100, 0)
    pen.write(op, font=("Arial", 24, "normal"))

# 定义等号按钮的点击事件
def onEqualClick():
    global operator, num1, num2, result
    if operator == "+":
        result = str(int(num1) + int(num2))
    elif operator == "-":
        result = str(int(num1) - int(num2))
    elif operator == "*":
        result = str(int(num1) * int(num2))
    elif operator == "/":
        result = str(int(num1) / int(num2))
    pen.goto(200, 0)
    pen.write(result, font=("Arial", 24, "normal"))

# 定义清除按钮的点击事件
def onClearClick():
    global operator, num1, num2, result
    operator = ""
    num1 = ""
    num2 = ""
    result = ""
    pen.clear()
    pen.write("0", font=("Arial", 24, "normal"))

# 画出计算器的数字和运算符按钮
pen.goto(-240, 80)
pen.write("1", font=("Arial", 24, "normal"))
pen.goto(-180, 80)
pen.write("2", font=("Arial", 24, "normal"))
pen.goto(-120, 80)
pen.write("3", font=("Arial", 24, "normal"))

pen.goto(-240, 20)
pen.write("4", font=("Arial", 24, "normal"))
pen.goto(-180, 20)
pen.write("5", font=("Arial", 24, "normal"))
pen.goto(-120, 20)
pen.write("6", font=("Arial", 24, "normal"))

pen.goto(-240, -40)
pen.write("7", font=("Arial", 24, "normal"))
pen.goto(-180, -40)
pen.write("8", font=("Arial", 24, "normal"))
pen.goto(-120, -40)
pen.write("9", font=("Arial", 24, "normal"))

pen.goto(-240, -100)
pen.write("0", font=("Arial", 24, "normal"))

pen.goto(0, 80)
pen.write("+", font=("Arial", 24, "normal"))
pen.goto(0, 20)
pen.write("-", font=("Arial", 24, "normal"))
pen.goto(0, -40)
pen.write("*", font=("Arial", 24, "normal"))
pen.goto(0, -100)
pen.write("/", font=("Arial", 24, "normal"))

pen.goto(120, 0)
pen.write("=", font=("Arial", 24, "normal"))

pen.goto(240, 0)
pen.write("C", font=("Arial", 24, "normal"))

# 给按钮绑定点击事件
canvas.onclick(lambda x, y: onButtonClick(1) if -240 <= x <= -180 and 60 <= y <= 100 else None)
canvas.onclick(lambda x, y: onButtonClick(2) if -180 <= x <= -120 and 60 <= y <= 100 else None)
canvas.onclick(lambda x, y: onButtonClick(3) if -120 <= x <= -60 and 60 <= y <= 100 else None)
canvas.onclick(lambda x, y: onButtonClick(4) if -240 <= x <= -180 and 0 <= y <= 40 else None)
canvas.onclick(lambda x, y: onButtonClick(5) if -180 <= x <= -120 and 0 <= y <= 40 else None)
canvas.onclick(lambda x, y: onButtonClick(6) if -120 <= x <= -60 and 0 <= y <= 40 else None)
canvas.onclick(lambda x, y: onButtonClick(7) if -240 <= x <= -180 and -60 <= y <= 0 else None)
canvas.onclick(lambda x, y: onButtonClick(8) if -180 <= x <= -120 and -60 <= y <= 0 else None)
canvas.onclick(lambda x, y: onButtonClick(9) if -120 <= x <= -60 and -60 <= y <= 0 else None)
canvas.onclick(lambda x, y: onButtonClick(0) if -240 <= x <= -180 and -120 <= y <= -80 else None)
canvas.onclick(lambda x, y: onOperatorClick("+") if -60 <= x <= 60 and 60 <= y <= 100 else None)
canvas.onclick(lambda x, y: onOperatorClick("-") if -60 <= x <= 60 and 0 <= y <= 40 else None)
canvas.onclick(lambda x, y: onOperatorClick("*") if -60 <= x <= 60 and -60 <= y <= 0 else None)
canvas.onclick(lambda x, y: onOperatorClick("/") if -60 <= x <= 60 and -120 <= y <= -80 else None)
canvas.onclick(lambda x, y: onEqualClick() if 60 <= x <= 120 and -40 <= y <= 40 else None)
canvas.onclick(lambda x, y: onClearClick() if 180 <= x <= 240 and -40 <= y <= 40 else None)

# 运行程序
canvas.mainloop()

程序运行后，你可以在窗口中看到一个简单的计算器界面。你可以通过点击数字和运算符按钮来输入计算式，并且点击等号按钮来计算结果。点击清除按钮可以清空所有状态变量，重新开始计算。

注意，这个程序只支持整数计算。如果你需要支持浮点数计算，可以将 `int()` 函数改为 `float()` 函数。
