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. 其返回值类型为size_t,在头文件stddef.h中定义。这是一个依赖于编译系统的值,一般定义为 typedef unsigned int size_t; 世上...

Python 本身没有数组这个说法, 有的就是list和tuple, list就具有其他语言中的数组特性. 至于list和tuple的区别,在于list可以在运行时修改内容和大小,tuple在首次创建和赋值后, 不可以再次修改内部的内容 不过python 有提供一个array模块,用于提供基本数字,字符类型的数组.用于容纳字符号,整型,浮点等基本类型. 这种模块...
letting user-defined classes override the copying operation or the set of components copied. This module does not copy types like module, method, stack trace, stack frame, file, socket, window, array, or any similar types. It does “copy” functions and classes (shallow and deeply), by ret...
Return the “identity” of an object. This is an integer which is guaranteed to be unique and constant for this object during its lifetime. Two objects with non-overlapping lifetimes may have the sameid()value. CPython implementation detail:This is the address of the object in memory. ...

此类的函数还有很多,比如排序函数sorted(),类型函数type(),位数函数round(),打印函数print()等,和len()一样,这些都是python的内置函数。 之所以没有像Java array对象将size设置为类方法,因为python语言特性就是要追求简洁性和一致性,能一种方法搞定的绝不多费功夫,哪怕牺牲一点安全性。
