美国州名游戏：输入州名后地图图片消失问题求助

问题根源在于同一个海龟对象既用来显示地图，又用来写州名：当你调用turtle.hideturtle()时，显示地图的海龟被隐藏，导致地图随之消失。

修改方案 #

创建两个独立的海龟实例，各司其职：

• 一个专门负责显示地图，全程保持可见
• 另一个专门负责在地图上书写州名，仅处理文字输出逻辑

修改后的完整代码 #

import pandas
from turtle import Turtle, Screen

# 创建两个独立的海龟实例
map_turtle = Turtle()  # 负责显示地图
writer_turtle = Turtle()  # 负责书写州名
screen = Screen()

# 加载并显示地图
screen.title("U.S. States Game")
image = "blank_states_img.gif"
screen.addshape(image)
map_turtle.shape(image)

# 初始化写文字的海龟：隐藏光标、抬笔（避免移动时留下轨迹）
writer_turtle.hideturtle()
writer_turtle.penup()

# 处理州名数据
data = pandas.read_csv("50_states.csv")
all_names = data.state.to_list()
name_list = []

# 游戏主循环
while len(name_list) < 50:
    guess_name = screen.textinput(title=f"{len(name_list)}/50 States Correct",
                                  prompt="Input the name of a state ").title()
    if guess_name == "Exit":
        # 用列表推导式简化缺失州名的筛选
        missing_states = [state for state in all_names if state not in name_list]
        pandas.DataFrame(missing_states).to_csv("missing_states.csv")
        break

    if guess_name in all_names:
        name_list.append(guess_name)
        row_data = data[data.state == guess_name]
        writer_turtle.goto(int(row_data.x), int(row_data.y))
        writer_turtle.write(guess_name)

关键修改说明 #

1. 拆分原海龟对象为map_turtle和writer_turtle，避免地图显示与文字输出互相干扰
2. 提前初始化写文字海龟的状态（隐藏、抬笔），无需每次猜对州名都重复设置
3. 保留原有所有游戏逻辑，同时确保地图全程保持显示
