## 一.Python str 函数介绍 ##

在 [Python][Python 2] 中 [str][] 即可以表示 [**字符串**][Link 1]  [**str** ][Link 1]类型，也可以作为一个内置函数，**可以直接将其他数据类型强制转为字符串类型**，语法如下：

'''
    参数：
        object — python数据类型对象；
    
    返回值: 返回一个str类型的变量；
    '''
    
    str(object)

## 二.Python str 函数使用 ##

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

    # 案例1: 将整形或者浮点数类型转为str字符串类型
    print(type(str(3.5)))
    print(str(3.5))
    print("***"*20)
    
    # 案例2: 将字典转为str字符串类型
    dict1 = {'www': 'shuopython.com', 'google': 'google.com'}
    print(type(str(dict1)))
    print(str(dict1))
    print("***"*20)
    
    # 案例3: 将列表转为str字符串类型
    list1 = [1, 2, 3, 4]
    print(type(str(list1)))
    print(str(list1))
    
    
    '''
    输出结果：
    
    <class 'str'>
    3.5
    ************************************************************
    <class 'str'>
    {'www': 'shuopython.com', 'google': 'google.com'}

    <class 'str'>
    [1, 2, 3, 4]
