## 一.Python id 函数简介 ##

每个人都有对应的身份证号码，并且唯一！反之亦然，一个身份证号码必然对应一个人；

\*\*[id 函数][id]返回对象的唯一标识符，标识符是一个整数，该标识符就是存放该对象的内存地址；\*\*语法如下：

'''
    参数说明：
        object — 对象
    返回值 : 返回object对象内存地址.
    '''
    id([object])

## 二.Python id 函数使用 ##

**可以通过 [Python][Python 2] 内置函数 id 查看对象的内存地址**，示例代码如下：

# !usr/bin/env python
    # !usr/bin/env python
    # -*- coding:utf-8 _*-

    """
    a = 10     # 整数类型
    b = False  # bool类型
    c = 10.55  # 浮点数类型
    d = "123"  # 字符串类型
    e = ('apple', 'banana', 'cherry') # 元祖类型
    f = {"name":"zhangsan","age":18}  # 字典串类型
    g = [456,False,"123"]             # 列表类型
    
    print(id(a))
    print(id(b))
    print(id(c))
    print(id(d))
    print(id(e))
    print(id(f))
    print(id(g))
    
    '''
    输出结果：
    140682288640544
    140682288407904
    140682280310736
