#2 Created at ... [Delete] [Delete and Lock User]

改成

while n<=len(L):

更好

#3 Created at ... [Delete] [Delete and Lock User] 
print('hello, %s!' % name)

请问大神，

%s!' % name这一段的意思，为何结果!会在name后面

一帆大湿

#4 Created at ... [Delete] [Delete and Lock User]

改成：

while n<=len(L):

是错的，因为len(L)=3

所以应该是：

while n<len(L):

这样代码的结果才是对的
