Python3中,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 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 str转换成bytes: In [9]: str1='人生苦短,我用Python!' In [10]: type(str1) Out[10]:...
Python 的字节序列有两种: 可变的 bytearray 和不可变的 bytes. bytes 或 bytearray 对象的各个元素是介于 0~255(含)之间的整数 也就是说字节序列的最小单位是字节, 而不像字符串那样最小单位是 Unicode 字符. 拿上面的例子来说 café 这个字符串长度为4, 把它用 utf-8 编码后为 b'cafxc3xa9'.可见最...

1、bytearray和bytes不一样的地方在于,bytearray是可变的。 str ='人生苦短,我用Python!'bytes=bytearray(str.encode()) bytes= bytearray(b'\xe4\xba\xba\xe7\x94\x9f\xe8\x8b\xa6\xe7\x9f\xad\xef\xbc\x8c\xe6\x88\x91\xe7\x94\xa8Python!') str=bytes.decode()print(str) 输出: '人...

3.谈下python的GIL GIL 是python的全局解释器锁,同一进程中假如有多个线程运行,一个线程在运行python程序的时候会霸占python解释器(加了一把锁即GIL),使该进程内的其他线程无法运行,等该线程运行完后其他线程才能运行。如果线程运行过程中遇到耗时操作,则解释器锁解开,使其他线程运行。所以在多线程中,线程的运行仍是...

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 ori...
基于python的struct模块实现简单的ByteBuf 写在前面 在网络编程中需要将消息序列化为二进制序列打包传输。python标准库中的struct模块提供了pack、unpack等函数将基本数据类型转换为对应的bytes数组。使用pack、unpack需要在传参是需要关注字节序(大小端)、格式等,其中字节序有@、=、<、>、!五种,格式约21种,使用成本...
