python字符串如何转化为列表

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

['1', '2', '3', '4', '5']

['123', 'sjhid', 'dhi']

['www', 'google', 'com']

>>> image ='1.jsp,2.jsp,3.jsp,4.jsp'

>>> image_list = image.strip(',').split(',')

>>> print image_list

['1.jsp', '2.jsp', '3.jsp', '4.jsp']

>>>
