Python 字符串(str)与列表(list)互相转换的方法,一定要会

1.str to 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']

2. list to str
