Blockchain is easy to learn
blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
characteristics of blockchain technology
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
security. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
300 Philippine Peso = 41.82 RMB yuan
{rrrrrrr}
the exchange rate is constantly changing. Please refer to the exchange rate you need at that time when you use it. When you exchange it at the bank counter and online banking, it is based on the real-time quotation at that time
for example, for the latest exchange rate query, you can input & quot; Exchange rate of Philippine dollar to RMB;, You can directly see the latest exchange rate
another way:
1. Foreign exchange market trend is attached to the futures and foreign exchange quotation software
2. Foreign exchange quotation is also available on major financial websites
3. Exchange rate can also be queried through the foreign exchange inquiry tool of mobile phone
4. Most of the mobile futures quotation software also has the exchange rate quotation of major currencies
why Python is easy to learn is determined by its own characteristics. As an interpretive language, there is no compilation link in the process of Python development. Although Python sacrifices the efficiency of some machines, it improves the compilation efficiency of human beings. Therefore, we often regard Python as a language closer to natural language, and its logic is also very close to human logic. Even beginners can easily understand the syntax and logic of Python. Moreover, python has a large number of standard libraries, so only a few lines of code can achieve a function. Mastering Python can rece the workload of conventional development because of a large number of third-party libraries. This is the learning advantage of Python itself, and also why it is favored by developers and beginners<
Python learning plan:
of course, even if Python is a novice friendly programming language, it also needs scientific methods and their own efforts to learn and master it. So how do we plan our Python study plan? Here is a brief introction to the basic grammar learning syllabus of Bo Xue Gu. You can refer to it. First of all, learning content involves variables, operators, input and output and conditions, as well as the basic syntax of loop statements. There are seven learning stages in total. They are the first Python program, annotation, variable, input and output, operator, if, while, for, string, list and dictionary, tuple. Learners without any software programming foundation or Python experience can master Python's variables, input and output, operators, conditions, loop statements and other syntax knowledge through the basic Python syntax tutorial of erudition valley<
Python learning schele:
as for how long to learn python, it depends on how to learn and how much to learn. If we want to achieve the level of employment through zero basis self-study, we need about half a year to a year according to the difference between everyone's understanding ability and learning ability. If you choose training, with the guidance and leadership of the instructor, you can avoid many detours, and the learning efficiency will be higher. You can master Python in less than half a year. Taking the course of Python employment class in Bo Xue Gu as an example, it covers all the technologies needed in the fields of computer principles, network, web front-end, back-end, architecture, database, project deployment, data acquisition, data extraction, data cleaning, data analysis, data mining, machine learning, deep learning, image recognition, etc, With the goal of two core employment directions + multi field employability training, students can be competent for Python development job after completing the course.
Share the python learning path
the first stage is Python foundation and Linux database. This is the beginning stage of python, and also an important stage to help students lay a good foundation. You need to master Python basic syntax rules and variables, logic control, built-in data structure, file operation, advanced functions, moles, common standard library moles, functions, exception handling, MySQL use, coroutine and other knowledge points
learning objectives: master basic Python syntax and basic programming ability; Master the basic operation commands of Linux, master the advanced content of MySQL, and complete the projects of bank ATM system, English Chinese dictionary, lyrics parser, etc
the second stage is full web stack. In this part, you need to master HTML, CSS, JavaScript, jQuery, bootstrap, web development foundation, Vue, flag views, flag template, database operation, flag configuration and other knowledge
learning objectives: master the web front-end technology content, master the web back-end framework, skillfully use flash, tornado, Django, and complete the data monitoring background project
The third stage is data analysis + artificial intelligence. This part is mainly to learn the knowledge points related to crawler. You need to master the knowledge of data capture, data extraction, data storage, crawler concurrency, dynamic web page capture, scrapy framework, distributed crawler, crawler attack and defense, data structure, algorithm, etclearning objective: to master crawler, data acquisition, data organization and algorithm advanced and artificial intelligence technology. It can complete crawler attack and defense, image mosaic, movie recommendation system, earthquake prediction, artificial intelligence project and other stage projects
The fourth stage is advanced. This is a python advanced knowledge point. You need to learn project development process, deployment, high concurrency, performance tuning, go language foundation, blockchain introction, etclearning objectives: master the technology of automatic operation and maintenance and blockchain development, and complete the automatic operation and maintenance projects, blockchain and other projects
according to the python learning roadmap above, you can basically become a qualified Python development engineer. Of course, if you want to quickly become the elite talents of enterprises, you need good teachers to guide you, and you need more projects to accumulate practical experience
First of all, learn the basic syntax of python, the understanding of object-oriented programming and programming pattern, the basis of Python data analysis, Python Network programming, python concurrency and efficient programming, etc. Through the early Python learning to understand and master the use of constant variables, the use of operators, the use of process control, and finally master the basic content of Python programming language. And will study the common data structure and the corresponding algorithm, pay attention to the table processing, tree structure processing knowledge
Then, to determine a specific learning direction, python can be applied to web development, crawler, data analysis, artificial intelligence development and other fields. Different learning directions need to learn different knowledge structures, which can be matched with their own ecation background, interest points and corresponding job recruitment requirements to select the most suitable direction Web development, crawler, data analysis, artificial intelligence, no matter which direction you are interested in, you can learn python, which is very friendly for zero basic programming learners.
