排查与解决方法 #

这个错误的核心原因是Python标准库的numbers模块被破坏或被同名文件覆盖，导致decimal模块依赖的numbers.Number无法正常访问。按以下步骤修复：

• 检查并移除同名文件
  查看代码所在的c:\Users\Lenovo\Desktop\Code fs\目录下，是否存在名为numbers.py的文件。如果有，直接删除或重命名（比如改成my_numbers.py），避免覆盖系统标准库模块。

• 修复损坏的标准库
  如果目录中没有同名文件，说明numbers模块本身已损坏。重新安装Python 3.9：

  1. 卸载当前Python 3.9版本
  2. 下载对应版本的官方安装包重新安装
  3. 安装完成后，执行pip install requests重新安装requests库

• 验证修复结果
  打开Python交互环境，输入以下命令测试：

  import numbers
  print(numbers.Number)
  

  若能正常输出<class 'numbers.Number'>，说明模块已恢复，再运行你的代码即可。
