Python版Hangman游戏：错误猜测时逐步显示绞刑架的实现问题

问题根源 #

你的代码有三个核心问题导致绞刑架无法逐步更新：

• displayScaffold函数参数错误：应该传入当前错误次数wrong，而非最大错误次数MAX_WRONG
• 绞刑架阶段顺序颠倒：错误次数为0时应显示空绞刑架，但你定义的stages数组第一个元素是完整绞刑架，最后一个才是空的
• 未在每次错误后重新渲染绞刑架，且初始显示时误用了MAX_WRONG作为参数

修正后的完整代码 #

import random

def displayScaffold(wrong_guesses):
    """根据错误猜测次数返回对应阶段的绞刑架图形"""
    # 顺序调整：索引0对应0次错误（空绞刑架），索引6对应6次错误（完整绞刑架）

关键修改说明 #

1. 函数参数与docstring优化：
   • 将函数参数改为wrong_guesses（当前错误次数），并添加规范的docstring说明功能
2. 调整stages顺序：
   • 让索引0对应0次错误的空绞刑架，索引6对应6次错误的完整绞刑架，保证错误次数与图形阶段一一对应
3. 更新渲染时机：
   • 初始显示时传入wrong=0，显示空绞刑架
   • 每次错误后调用displayScaffold(wrong)，实时更新绞刑架图形
   • 可选：猜对后也保留绞刑架显示，让界面更连贯
4. 小细节优化：
   • 用f-string替代旧式字符串拼接，代码更简洁
   • 修正了原代码中斜杠的显示错误（/|/改为/|\，符合标准绞刑架图形）
