byte_stream=byte_value 1. 代码解释: byte_value是步骤2中得到的字节类型值 将byte_value赋值给byte_stream变量,即得到最终的字节流 完整代码示例 hex_string="1a2b3c"decimal_value=int(hex_string,16)byte_value=decimal_value.to_bytes((decimal_value.bit_length()+7)//8,'big')byte_stream=byte_value...
下面是一个完整的示例代码,演示了如何将字符串转换成十六进制字节流: defstring_to_hex(string):byte_stream=bytes(string,'utf-8')hex_string=''.join([hex(byte)[2:].zfill(2)forbyteinbyte_stream])returnhex_string string="Hello, world!"hex_string=string_to_hex(string)print(hex_string) 1. 2...

s.send(string[,flag]) 发送TCP 数据。将 string 中的数据发送到连接的套接字。返回值是要发送的字节数量,该数量可能小于 string 的字节大小。 s.sendall(string[,flag]) 完整发送 TCP 数据。将 string 中的数据发送到连接的套接字,但在返回之前会尝试发送所有数据。成功返回 None,失败则抛出异常。 s.recvfr...
StringIO的源码位于Modules/_io/stringio.c。作为一个C级对象,我们首先来看StringIO的object struct定义: 接下来的代码来自https://github.com/python/cpython的main分支,本文写作时的版本号为Python 3.12.0 Alpha 4。下同 typedefstruct{ PyObject_HEAD ...

On the application side, if we wanted to turn a stream input we’ve received into a string, we’d want to write something like this: For Python 2.7 readstr = environ['wsgi.input'].read()# returns str object For Python 3.5 readbytes = environ['wsgi.input'].read()# returns bytes ob...

This feature can be used to implement custom decoders. If ``object_hook`` is also defined, the ``object_pairs_hook`` takes priority. ``parse_float``, if specified, will be called with the string of every JSON float to be decoded. By default this is equivalent to ...
先使用calsize计算fmt的大小,然后每次转换string中长度为每个fmt对饮大小的字节,返回的是每次unpack产生的值组成的一个unpack_iterator。 import struct int_byte1 = b'\x01\x00\x00\x00\x02\x00\x03\x00\x00\x00' fmt = "=IHI" rest = struct.iter_unpack(fmt, int_byte1) ...
