Practice:

#注册
#输入账号密码
#如果账号存在的, the hint has been registered, and if it does not exist, let him register
#不能为空
#用户名长度6-12
#最多输入3次
all_user=[' Niuhanyang ', ' Poon ', ' Zhang San ', ' Li 4,435,345 ', ' 123456 ']
# print (len (all_user)) #取个数, length
For I in range (3):
    Username=input (' Please enter account: '). Strip ()
    If Len (username) >5 and len (username) <13:
        If All_user.count (username) >0:
            Print (' User name already exists ')
        Else
            Print (' Register Now ')
            Break
    Else
        Print (' username length is not legal! Length between 6-12! ‘)
