SyntaxError: Non-UTF-8 code starting with '\xbd' in file C:\Users\Joker\PycharmProjects\hello\main.py on line 11, but no encoding declared; see https://python.org/dev/peps/pep-0263/ for details

这个错误通常是由于文件中包含非 UTF-8 编码的字符所导致的。Python 默认使用 UTF-8 编码，如果文件中有非 UTF-8 编码的字符，就会导致解释器无法正确读取文件。

要解决这个问题，可以在文件的开头添加一个编码声明，告诉解释器文件所使用的编码。例如，在文件的第一行添加以下代码：

# -*- coding: utf-8 -*-

这个声明告诉解释器，文件使用的编码是 UTF-8。如果你使用的是其他编码，可以将 utf-8 替换为相应的编码名称。

SyntaxError: Non-UTF-8 code starting with '\xd2' in file F:\Nmuis\main.py on line 7,

这个错误通常是因为文件编码格式与Python解释器不匹配所导致的。Python默认使用UTF-8编码格式，而你的代码中似乎包含了非UTF-8编码格式的字符。

可以尝试在文件开头添加以下注释来指定编码格式：

# -*- coding: utf-8 -*-

如果还是无法解决问题，可以尝试使用文本编辑器将文件另存为UTF-8编码格式。

SyntaxError: Non-UTF-8 code starting with

This error typically occurs when there is a non-UTF-8 character or encoding present in the code. It can happen when the code is saved with a different encoding than UTF-8, or when non-UTF-8 characters are copied and pasted into the code.

To fix this error, you can try the following steps:

1. Check the encoding of the file and make sure it is UTF-8. You can do this by opening the file in a text editor and checking the encoding settings.

2. If the file is not UTF-8, save it with UTF-8 encoding.

3. If you copied and pasted code from another source, make sure that the source is using UTF-8 encoding.

4. If the error persists, check the specific line of code where the error occurred and see if there are any non-UTF-8 characters present. Remove or replace these characters with UTF-8 characters.

5. If you are still having issues, try using a code editor that supports UTF-8 encoding and has the ability to convert files to UTF-8.
