那个莫名其妙的"which must be a string of length 256"就不用深究了,反正table就是由string.maketrans方法生成的,对于string.maketrans方法,这里有个更清晰的解释,如下: string.maketrans(intab, outtab) --> This method returns a translation table that maps each character in the intab string into the c...

字节串(bytes)和字符串(string)的对比: 字符串由若干个字符组成,以字符为单位进行操作;字节串由若干个字节组成,以字节为单位进行操作。 字节串和字符串除了操作的数据单元不同之外,它们支持的所有方法都基本相同。 字节串和字符串都是不可变序列,不能随意增加和删除数据。
