import json
###检查输入的用户是否被锁
def UserLogin():
    UserFile = open("UserFile.text", "rb")
    UserInput = input("请输入账号：")
    UserRead = json.load(UserFile)
    for UserRead_ in UserRead:
        if UserRead_["UserID"] == UserInput:
            print("[%s]该用户亦被锁，请联系管理员！"%UserInput)
            exit()
        else:
            UserPass(UserInput)
    UserFile.close()
lock_List = []
###用户锁定读取文件
def Userlock(lock,UserInput):
    for lock_list in lock:
        lock_List.append(lock_list)
    UserLock(lock_List,UserInput)
###用户锁定修改
def UserLock(lock_List,UserInput):
    lock_List.append({"UserID":UserInput})
    UserLock__ = open("UserFile.text","w")
    UserLock_ = json.dump(lock_List,UserLock__)
    print("您的[%s]账户被冻结，请联系管理员!!!"% UserInput)
    UserLock__.close()
###检查用户输入的账号是否存在，如果存在就输入密码，如果不存在就提示用户
def UserPass(UserInput):
    UserPassRead = open("UserReadFile.text","rb")
    User_PassRead = json.load(UserPassRead)
    count_1 = 0

                User_Pass = input("请输入密码：")
                if Userread_["UserPass"] == User_Pass:
                    print("[%s]欢迎您"%UserInput)
                    exit()
                elif count_ < 3:
                    print("密码错误，请重新输入！！您还剩[%s]" % (3 - count_))
                elif count_ == 3:
                    k = open("UserFile.text","rb")
                    lock=json.load(k)
                    Userlock(lock,UserInput)
                    k.close()
                    exit()
        elif len(Userread_) == count_1:
            print("[%s]该账号还未注册"%UserInput)
            print("您可以前往注册（a）/重新输入账号（b）")
            Input_ = input("a/b:")
            if Input_ == "a":
                exit()
            else:
