【Tkinter】用Python写一个抽奖系统3.0

        def keys():
            global flag1
            key=var1.get()
            if key==user_keys:

            else:
                var1.set('管理员密码错误')

录入礼物

        def gifts():
            global flag1
            if flag1==1:
                gift=var2.get()

                if gift!='录入成功' or gift!='录入失败':

            else:
                var2.set('请先输入管理员密码')

退出管理员

        def end():
            global flag1
            flag1=0

抽奖系统

        def choice():
