python 字符串（str）和列表（list）的互相转换

1.str >>>list

    str1 = "12345"  
    list1 = list(str1)  
    print list1  
      
    str2 = "123 sjhid dhi"  
    list2 = str2.split() #or list2 = str2.split(" ")  
    print list2  
      
    str3 = "www.google.com"  
    list3 = str3.split(".")  
    print list3  


输出为：

['1', '2', '3', '4', '5']  
['123', 'sjhid', 'dhi']  
['www', 'google', 'com']
