Python list和str互转

1. str转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

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

2. list转str

str4 = ''.join(list3)
print (str4)
str5 = '.'.join(list3)
print(str5)
str6 = ' '.join(list3)
print(str6)

输出

wwwgooglecom
www.google.com
www google com
