对比使用pack方法打包,pack_into 方法一直是在对prebuffer对象进行操作,没有产生多余的内存浪费。另外需要注意的一点是,pack_into和unpack_from方法均是对string buffer对象进行操作,并提供了offset参数,用户可以通过指定相应的offset,使相应的处理变得更加灵活。例如,我们可以把多个对象pack到一个buffer里面,然后通过指定不...
import year print("bin.py通常作为python的入口文件") 1. 2. 运行bin.py 输出: 来自__ init__.py bin.py通常作为python的入口文件 注:bin.py运行时选运行了__ init__.py下的代码 3、模块的导入 一个模块只会被导入一次,不管你执行了多少次import。这样可以防止导入模块被一遍又一遍地执行 3.1、同Packag...
用法示例：import struct# 创建一个 bytearray 缓冲区buffer = bytearray(8)# 将整数和浮点数打包并写入缓冲区指定位置struct.pack_into('i f', buffer, , 42, 3.14)print(buffer) # 输出：bytearray(b'*\x00\x00\x00\xc3\xf5H@')unpack(format, buffer)函数定义：从给定的缓冲区中按照指定的格式解...
