python中pop()与split()的用法
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'] 15 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
