A built-in string object (plain or Unicode) is a sequence of characters
used to store and represent text-based information (plain strings are
also sometimes used to store and represent arbitrary sequences of
binary bytes). £¨Õª×Ô¡¶Python in a NutShell¡·£©
QByteArray can be used to store both raw bytes (including '"0's) and traditional 8-bit '"0'-terminated.£¨Õª×Ô¡¶PyQtÊֲᡷ£©
