1. I don't quite understand what you mean. If you register in the online wallet and your mobile phone is changed, you can change your mobile phone number directly in your personal settings or contact customer service. If it's registered in the trading platform and needs to be changed, it's easier. Just contact customer service directly or modify your own personal settings.
2. If the cell is 3.7V, the energy is 3.7V * 5Ah = 18.5wh, and the primary power is 1000WH. Considering the charging conversion efficiency, it is assumed that 80% is 23wh, that is, 0.023 kwh. At present, the cell power of mobile phone is relatively large, generally about 3000mAh is more, in terms of 3000mAh, it is full once at most.
3. We need to understand some mathematical models, such as statistical analysis, artificial intelligence algorithm and so on. Its essence is to use mathematical models to analyze the potential laws of data, find trading opportunities, and use computer programs to search for trading opportunities and complete automatic trading. There is no ready-made software to do this, because it needs to build a professional platform, which is not a person can complete
there are some domestic software, such as great wisdom, which provides quantitative analysis, and some software which provides programmed trading of stocks and futures. But in fact, this is not a real quantitative transaction. In fact, it is very difficult to make a pure quantitative investment software suitable for indivial investors, because the quantitative strategy does not have the established and inevitable law like the traditional fundamentals and technology. He needs to cross multi-disciplinary, multi field to mine the rules of data, and then use the rules to trade. However, the potential laws of different time and space data are not consistent, so it is difficult to standardize the quantitative process
if you are a computer or math professional, you can consider using C, C + +, SQL and other languages, and other software such as MATLAB / SAS. No matter what kind of software, to achieve quantitative trading, it must need a certain modeling basis and programming basis, among which the most important thing is mathematical ability.

5. 1. Network programming. Network programming is everywhere in life and development. Where there is communication, there is network. It can be called the "cornerstone" of all development. For all programming developers, we must know what it is and why it is, so the network part will be deeply analyzed from the bottom of protocol, packet, unpacking and so on
2. Crawler development. All the network data as resources, through the automatic program for targeted data collection and processing. Crawler development project includes spanning anti crawler strategy, high-performance asynchronous IO, distributed crawler and so on, and analyzes the source code of scrapy framework, so as to understand its principle and realize the custom crawler framework
3. Web development. Web development includes two parts: front-end and back-end. The front-end takes you from "black and white" to "color" world, and develops dynamic web pages by hand; The back-end part takes you from 10 lines of code to tens of thousands of lines to implement and use your own micro web framework. The framework explanation covers the knowledge of data, components, security and other fields. You can understand its working principle from the bottom and control any mainstream web framework in the instry
4. It automation development. It operation and maintenance automation is a group of strategies that transform static equipment structure into dynamic and elastic response according to it service demand. The purpose is to rece manual intervention, rece personnel cost and error probability, and take you to develop the most commonly used projects in the enterprise, from the design level, framework selection, flexibility, scalability, fault handling, etc As well as how to optimize and other levels of contact with real and real cases from major Internet companies, such as: Fortress machine, CMDB, network monitoring, host management, etc

About self-learning python, my three biggest personal experiences are as follows:
< UL > find a simple and easy to understand tutorial with better routines, and read it from beginning to end. Don't read many books, focus on one. Type all the routines in it by hand to understand why. I was reading "concise Python tutorial", but this book is not very suitable for beginners with zero basis
find an actual project to practice. I had to learn Python because I wanted to build a website. The effect of this condition is much better than that of learning a new language. So it's best to have real projects to do. Can find a few students to do a website and so on. Note that a real project is not necessarily a commercial project. It's also a real project to write a blog website that you can only use. The key is to complete the core functions
it's better to find someone who already knows python. Ask him some advice on Learning Planning (Shang is also a way), and then ask him for advice where he is stuck. This will get twice the result with half the effort. But learn to search, learn how to ask questions better. No one is willing to help you with your homework or answer the "easy to find" question

10. Compared with many other mainstream programming languages, it has better readability, so it is relatively easy to start. With its own various moles and rich third-party moles, we can write things faster without a lot of "repetitive wheel building" work. The configuration of the development environment is not very complicated. Both Mac and Linux have built-in python< In addition, as far as I know, many schools have begun to use Python to teach programming courses (such as my alma mater).
