Strings contain Unicode characters. Their literals are written in single or double quotes : 'python', "data". Bytes and bytearray objects contain single bytes – the former is immutable while the latter is a mutable sequence. Bytes objects can be constructed the constructor, bytes(), and from...
使用bytes列表可以方便地处理这些字节数据。 importsocket# 创建一个 socket 对象sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)# 连接到服务器sock.connect(("example.com",80))# 发送请求sock.send(b"GET / HTTP/1.1\r\nHost: example.com\r\n\r\n")# 接收响应response=sock.recv(1024)print(r...
Python中有一类特殊的对象称为字节类对象,可在多种二进制数据操作中使用,如图片、音频、视频数据,通过socket套接字发送数据,以及与C语言的API进行数据交互等等。 bytes 只负责以字节序列的形式(二进制形式)来存储数据,至于这些数据到底表示什么内容(字符串、数字、图片、音频等),完全由程序的解析方式决定。如果采用合...

Each item in bytes or bytearray is an integer from 0 to 255, and not a one-character string like in the Python 2 str. However, a slice of a binary sequence always produces a binary sequence of the same type—including slices of length 1. See Example 4-2. Example 4-2. A five-byt...

In python 3, bytes strings and unicodestrings are now two different types. Since sockets are not aware of string encodings, they are using raw bytes strings, that have a slightly differentinterface from unicode strings. So, now, whenever you have a unicode stringthat you need to use as a ...
