Python猜数字游戏猜对仍报错、重复输出相同结果问题求助

• 混淆赋值与比较运算符：所有更新用户猜测值的语句错误使用了比较运算符==而非赋值运算符=，导致guessnum变量始终保留第一次输入的值，后续判断都基于初始值运行，自然不会根据新输入更新提示。
• 缩进逻辑错误：Easy模式下while循环的判断逻辑没有正确缩进至循环块内，代码执行流程完全不符合预期。
• 难度次数配置错误：Hard模式设定为3次猜测，但循环条件while number < 2实际仅支持2次猜测，和需求不符。
• 大小写兼容问题：提示用户输入E/H选择难度，但判断逻辑仅匹配小写的e/h，用户输入大写字母会直接触发输入错误，同时还修复了初始不输入y时变量未定义的报错问题。
