unicode现在通常是使用两个字节来表示一个字符,但是其实它可以被看成一个字符集,它将所有字符都定义了一个唯一的ID,这样网络就能有一个统一的字符表,不再出现之前的需要相互转化的问题。 那么新的问题就是直接使用unicode来表示字符时,它有时候会浪费空间,在编码表中靠前的字符,例如英文字符,它前一字节就是0000,...
注意:在 Python 中,以普通方式(文本模式)打开或创建文件和以二进制格式打开或创建文件,主要有以下几点不同: 数据的读取与写入方式:在文本模式下,文件中的内容被视为字符串(在 Python 3 中为 Unicode 字符串),并且会自动处理平台特定的行结束符。在 Windows 上,行结束符为 \r\n,在 Unix/Linux 上为 \n。当...

With that declaration, all characters in the source file will be treated as having the encodingencoding, and it will be possible to directly write Unicode string literals in the selected encoding. The list of possible encodings can be found in the Python Library Reference, in the section oncode...
