您正在混合制表符和空格：

线表示制表符，点表示空格。Python将选项卡扩展到每第8列。你知道吗

不要混合制表符和空格，将制表符转换回空格，并将编辑器配置为仅使用空格进行缩进。你知道吗

您可以将大多数编辑器配置为仅使用空格进行缩进；这是Python styleguide (PEP 8)建议的：

Tabs or Spaces?

Never mix tabs and spaces.

The most popular way of indenting Python is with spaces only. The second-most popular way is with tabs only. Code indented with a mixture of tabs and spaces should be converted to using spaces exclusively. When invoking the Python command line interpreter with the -t option, it issues warnings about code that illegally mixes tabs and spaces. When using -tt these warnings become errors. These options are highly recommended!

For new projects, spaces-only are strongly recommended over tabs. Most editors have features that make this easy to do.
