Posted 2020-11-10 乐乐熊小妹

 1 imglist = [‘11.jpg‘,‘12.jpg‘,‘13.jpg‘,‘14.jpg‘,‘2.jpg‘,‘1.jpg‘,]
 2 print(str(imglist))
 3 a = str(imglist).split(".")
 4 print(a)
 5 fTail = a.pop()
 6 print("-------------------")
 7 print(fTail)
 8 print("----$%%%%%%%%---")
 9 print(a)
10 
11 # aList = [123, ‘xyz‘, ‘zara‘, ‘abc‘]
12 # print("A List : ", aList.pop())#默认去除最后一个元素,打印出A List :  abc
13 # print("B List : ", aList.pop(2))#去除下标为2的元素,打印出B List :  zara
14 # print (aList)#打印出[123,‘xyz‘]

16 #!/usr/bin/python3
17 
18 str = "this is string example....wow!!!"
19 print (str.split( ))
20 print (str.split(‘i‘,1))
21 print (str.split(‘w‘))

打印结果为
