  1. input 输入
  2. print 输出
  3. for 循环
    for x in range(0,6):
        if x<3:
            print("\nx:",x)
        else:
            continue
            print("\nhello")

     

     

    4. while 循环

print("欢迎登录,请输入您的帐号及密码(3次机会):\n")
name = "王强"
pwd = "123"
i = 0  #计数器
while i<3:
    username = input("\n账号:")
    userpwd = input("\n密码:")
    if username == name:
        if userpwd == pwd:
            print("\n——登录成功——")
            break
        else:
            print("\n*密码错误*")
    else:
        print("\n*账号错误*")
    i+=1
else:
    print("\n\t\t*\t*\t*\t请明天再来\t*\t*\t*")
