用python海龟画图实现小学数学题出题

这是一个基本的例子，可以用来实现小学数学题出题：

import turtle
import random

# 生成一个随机的小数
def get_random_number():
    return round(random.uniform(1, 10), 1)

# 生成一个随机的运算符
def get_operator():
    operators = ['+', '-', '*', '/']
    return random.choice(operators)

# 生成一个随机的数学题
def generate_question():
    num1 = get_random_number()
    num2 = get_random_number()
    operator = get_operator()
    if operator == '+':
        answer = num1 + num2
    elif operator == '-':
        answer = num1 - num2
    elif operator == '*':
        answer = num1 * num2
    elif operator == '/':
        answer = num1 / num2
    question = f'{num1} {operator} {num2} = ?'
    return question, answer

# 绘制一个答案方框
def draw_box(turtle):
    turtle.penup()
    turtle.goto(-50, -50)
    turtle.pendown()
    turtle.pensize(5)
    for i in range(4):
        turtle.forward(100)
        turtle.left(90)

# 绘制问题和答案
def draw_question(turtle, question):
    turtle.penup()
    turtle.goto(-50, 0)
    turtle.pendown()
    turtle.write(question, font=('Arial', 16, 'normal'))

def draw_answer(turtle, answer):
    turtle.penup()
    turtle.goto(-50, -25)
    turtle.pendown()
    turtle.write(f'Answer: {answer}', font=('Arial', 16, 'normal'))

# 主函数
def main():
    turtle.setup(500, 500)
    turtle.speed(0)
    turtle.hideturtle()

    question, answer = generate_question()
    draw_box(turtle)
    draw_question(turtle, question)

    # 等待用户输入答案
    user_answer = turtle.textinput('Question', 'What is the answer?')

    draw_answer(turtle, answer)

    # 检查用户答案是否正确
    if float(user_answer) == answer:
        turtle.write('Correct!', font=('Arial', 16, 'normal'))
    else:
        turtle.write('Wrong!', font=('Arial', 16, 'normal'))

    turtle.exitonclick()

if __name__ == '__main__':
    main()

这个程序会生成一个随机的数学题，并在屏幕上绘制一个方框和问题。用户需要在弹出的对话框中输入答案。程序会检查用户是否输入了正确的答案，并在屏幕上显示结果。
