Python文本冒险游戏缩进错误求助：SyntaxError无效语法

错误原因分析 #

• 第50行的input()语句未闭合引号和括号，直接导致语法中断
• 嵌套的if answer == "a"缩进错误，且未正确闭合代码块
• 末尾存在多余的else，没有对应的if语句匹配

修正后的完整代码 #

import random
room = random.randrange(100,400)
door = 0
closets = 0
inventorySlots = 0  # 修正拼写错误：invintory → inventory

关键修正点说明 #

1. 引号闭合：修复了input()语句缺失的闭合引号和括号，这是触发SyntaxError的直接原因
2. 缩进与代码块：将嵌套的if语句调整到正确缩进级别，确保代码块结构完整
3. 移除多余分支：删除末尾无对应if的else语句，解决语法不匹配问题
4. 新手友好优化：
   • 修正拼写错误，让变量名符合英文规范
   • 使用lower()处理输入，兼容大小写输入（比如"A"和"a"都能被识别）
   • 调整随机数范围，让灯光闪烁的逻辑能正常触发
   • 修正物品替换的逻辑描述，避免语义矛盾
