There is no difference; Python recognizes all 3. It looks for the pattern:
没有区别;Python承认所有3。它寻找模式:
coding[:=]\s*([-\w.]+)
on the first two lines of the file (which also must start with a #).
在文件的前两行(也必须以#开头)。
That's the literal text 'coding', followed by either a colon or an equals sign, followed by optional whitespace. Any word, dash or dot characters following that pattern are read as the codec.
这是文本“编码”，后面跟着冒号或等号，后面跟着可选的空格。在此模式下的任何单词、破折号或圆点字符都被视为编解码器。
The -*- is an Emacs-specific syntax; letting the text editor know what encoding to use. It makes the comment useful to two tools. VIM supports similar syntax.
-*是一种特定于emac的语法;让文本编辑器知道要使用什么编码。它使注释对两个工具有用。VIM支持类似的语法。
