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

为什么可以直接用digit将字符转化为数字呢？希望大家能解惑一下，谢谢

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

说错了，是为什么不能和digits一样

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

因为有的名字里同时有大写和小写，而你提供的字典里只有大写字母的key，所以当循环到小写字母的时候，会找不到对应的value，就报错了

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

明白了，谢谢^-^
