sizeof是C/C++中的一个操作符(operator)是也,简单的说其作用就是返回一个对象或者类型所占的内存字节数。 MSDN上的解释为: The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate types). This keyword returns a value of type size_t. ...
python字节串与int、float、string互转,字节串与元组、列表、字符串互转 bytes 对象是由单个字节构成的不可变序列。 由于许多主要二进制协议都基于 ASCII 文本编码,因此 bytes 对象提供了一些仅在处理 ASCII 兼容数据时可用,并且在许多特性上与字符串对象紧密相关的方法。
