编写一个控制台程序，模拟在ATM机的存款和取款过程，当输入给定的卡号和密码（初始卡号和密码到数据文件里查看）时，系统能登录ATM系统，根据用户的身份不同显示不同的程序界面；取款 　　每次取款金额只能为100的倍数，总额不超过2000元，不允许透支。且取款之后，要记录取款的金额和时间。 存款 　　每次存款金额只能为100的倍数，总额不超过2000元。 修改密码 　　新密码长度不小于6位，不允许出现6位完全相同的情况，只有旧密码正确，新密码符合要求，且两次输入相同的情况下才可以成功修改密码。(Write a console program to simulate the ATM deposits and withdrawals process, when you enter a given number and password (the initial number and password to the data file view), the system can log in ATM systems, according to the user' s identity different display different The program interface withdrawal amount each withdrawal can only be a multiple of 100, the total does not exceed 2,000 yuan, does not allow overdrafts. And withdrawals after the withdrawal of the amount to be recorded and time. Deposit Amount per Deposit only a multiple of 100, totaling no more than 2,000 yuan. Change Password New Password length not less than six, allowed six identical situation, only the old password is correct, the new password meets the requirements, and enter the same case twice before they can successfully change the password.)

说明：  本书以Python为样本，不仅介绍了编程的基本概念，还着重讲解了 编程语言的范式（面向过程、面向对象、面向函数），并把编程语言的 范式糅在Python中，让读者不仅学会Python，未来在学习其他编程语言 时也变得更加容易。(aking Python as a sample, this book not only introduces the basic concepts of programming, but also focuses on the programming language paradigm (process-oriented, object-oriented, function-oriented), and incorporates the programming language paradigm into Python, so that readers can not only learn Python, but also become easier to learn other programming languages in the future.)

说明：  信息科技经过 60 余年的发展，已经普及到社会生活的每一个角落。随着信息技术在国家治理、经济运行的方方面面的应用，大量的数据随之产生。而互联网技术的爆发式发展使得近年来产生的数据总量超过了人类以往产生的历史数据的总和，医疗行业的数据增长幅度尤为突出。 医疗大数据具有巨大的价值,尤其是在临床辅助诊疗和健康管理方面。医疗大数据已经上升到国家战略，同时也是全球学术界与产业界竞争的研究热点。如何利用这些医疗数据，挖掘数据的深层价值，是未来信息科技发展的趋势，也是医疗大数据技术产生的背景。(After more than 60 years of development, information technology has spread to every corner of social life. With the application of information technology in all aspects of national governance and economic operation, a large number of data are generated. The explosive development of Internet technology has made the total amount of data generated in recent years exceed the total amount of historical data generated by human beings in the past, and the growth rate of data in the medical industry is particularly prominent. Big medical data have great value, especially in clinical assistant diagnosis and health management. Big medical data has risen to national strategy, and it is also a research hotspot in the competition between global academia and industry. How to use these medical data to excavate the deep value of the data is the trend of the development of information technology in the future, and also the background of the emergence of medical big data technology.)
