python中的struct主要是用来处理C结构数据的,读入时先转换为Python的字符串类型,然后再转换为Python的结构化类型,比如元组(tuple)啥的~。一般输入的渠道来源于文件或者网络的二进制流。1.struct.pack()和struct.unpack() 在转化过程中,主要用到了一个格式化字符串(format strings),用来规定转化的方法和格式。 下面来谈谈主要的方法:1.1 struct.pack(fmt,v1,v2,.....) 将v1,v2等参数的值进行一层包装,包装的方法由fmt指定。被包装的参数必须严格符合fmt。最后返回一个包装后的字符串。1.2 struct.unpack(fmt,string) 顾名思义,解包。比如pack打包,
