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

一开始是这样写的： L = ['Bart', 'Lisa', 'Adam'] n=len(L) while n>0: n=n-1 print ('Hello',L[n],'!') 然后发现输出好像倒过来了。。。。然后改了一下

L = ['Bart', 'Lisa', 'Adam'] n=0 while n<3: print ('Hello',L[n],'!') n=n+1

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

如果列表中存在的元素非常多应该这么写 L = ['Bart', 'Lisa', 'Adam'] n=0 l=len(L) while n<l: print ('Hello',L[n],'!') n=n+1
