以下代码在python 2.7中运行良好: def GetMaxNoise(data, max_noise): for byte in data: noise = ComputeNoise(struct.unpack('=B',byte)[0]) if max_noise < noise: max_noise = noise return max_noise 其中数据是保存二进制数据的字符串(取自网络数据包)。我试图将它移植到Python 3中,我得到了以下...

For Python 2.x users: In the Python 2.x series, a variety of implicit conversions between 8-bit strings (the closest thing 2.x offers to a built-in binary data type) and Unicode strings were permitted. This was a backwards compatibility workaround to account for the fact that Python ...

<type 'str'> Python 3中 >>> type(b'xxxxx') <class 'bytes'> >>> type('xxxxx') <class 'str'> 区别 bytes是byte的序列,而str是unicode的序列。 str 使用encode方法转化为 bytes bytes通过decode转化为str str转换成bytes: In [9]: str1='人生苦短,我用Python!' ...

在Java中,字节数组可以存放负值,这是因为Java的byte类型的取值范围为-128到127之间,而在Python3中,bytes的取值范围为0到256。...Java: -127~128 Python:0~256 在某些场景下,比如AES加密时,会用到Key、IV(偏移量)等参数值的定义,在Java中有可能是如下的: public static byte[...来实现同样的加密算法则会出...
The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operations. The optional source ...
