2.0.3

1. Fix a crucial error where class attribute values were tampered with in the logic block for importing real code, which caused the last release to fail.
2. Fix a potential error where attempting to access the "ge" magic attribute would raise an exception if the magic attribute did not exist, but also existed in the `builtins` module.
3. Refactor (improve) the method of obtaining version information in `setup` by directly extracting it from `package.__doc__`, rather than opening a file.
4. Adjust the classification information of the open-source library on PyPi.

1.修复一个严重的错误，在导入真实代码的逻辑块中篡改类属性值的错误，这导致上次未成功发布版本。
2.修复一个可能发生的错误，在尝试获取 `ge` 的魔法属性时，如果该魔化属性不存在，同时该魔化属性又存在于 `builtins` 模块，将引发异常。
3.重构（改进） `setup` 中获得版本信息的方案，直接从 `package.__doc__` 中提取，而不再打开文件。
4.调整在PyPi上的开源库分类信息。
