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']  

3.list >>>str

str4 = "".join(list3)  
print str4  
str5 = ".".join(list3)  
print str5  
str6 = " ".join(list3)  
print str6
输出为：

wwwgooglecom  
www.google.com  
www google com
