1. What should I pay attention to when learning programming by myself?
Refine the goal: For self-study, a specific, achievable, and practical goal is very important, such as "learning Python programming" and "writing a web crawler".
What to learn and how to learn: Choose a suitable programming book or online course, and try to use various ways to understand the content of learning, such as coding exercises, practical writing, etc.
Practice and projects: During the learning process, try to write some small projects or solve some practical problems, which can not only deepen the understanding of a certain knowledge point, but also improve programming skills.
Planning and time management: combine study planning with time management, maintain motivation and enthusiasm, and try to keep learning every day as much as possible. After accumulation, you will have a great sense of accomplishment.
Find support and feedback: You can find some friends who are learning programming to support and communicate with each other. You can also post for help in online programming communities to get useful feedback and suggestions.
2. What language is good for programming beginners?
For beginners in programming, here are a few things to consider:
1. The richness and quality of learning resources: Choose a widely used programming language, and you can find many high-quality learning resources and tutorials on the Internet, which is convenient for beginners to learn.
2. Simple and easy-to-understand language: Choose a programming language with simple and easy-to-understand grammar and easy to learn, so that you can master the basic concepts and coding techniques of programming faster.
3. Practicability and prospects: It is necessary to choose a programming language with practical application and broad prospects, so that more project practice and job opportunities can be found during the learning process.
Based on the above points, the following programming languages are suitable for beginners to learn:
1. Python: Python is an easy-to-learn, powerful, and widely-used programming language that can be used in data analysis, machine learning, web development, and scientific computing.
2. JavaScript: JavaScript is a programming language widely used in web front-end development, which can be used to develop web applications, browser extensions, and mobile application development.
3. Ruby: Ruby is an object-oriented programming language with concise and easy-to-understand syntax, which is very suitable for beginners to get started quickly. Ruby is mainly used in web development, especially the Ruby on Rails framework.
In short, the above programming languages are easy to learn, widely used, and practical. Beginners can choose a programming language that suits them according to their interests and learning goals.
3. In programming, what good habits are worth sticking to from the beginning?
There are a few good habits that programmers should stick to from the very beginning:
1. Standardized naming of variables, functions, and classes: Standardized naming can make the code easier to understand and maintain, while also improving code readability and reusability, and reducing the possibility of errors.
2. Write comments: Comments are very important. They can facilitate other people to understand the code, and it can also facilitate developers to quickly locate and reduce the chance of making mistakes when searching and maintaining code.
3. Modular programming: Modular programming refers to splitting the code into small, independent modules, and each module achieves a single function or purpose as much as possible. This method can greatly improve the reusability of the code. Reduce the cost of code modification.
4. Use version control: Before each programming, perform code backup in time, and use a version control tool, such as Git, SVN, etc., to maintain and trace version history records, and at the same time facilitate collaborative development and improve development efficiency.
5. Organize the code structure in a timely manner: tidying up the code structure can reduce code confusion, improve readability, and also enable better code management and maintenance.
6. Write test code: Testing is an integral part of programming. Writing test code can help developers better understand the code and deal with possible errors. At the same time, it can also prevent the original function from being destroyed when the code is changed.
In short, sticking to these programming habits can improve code quality, reduce errors, better maintain code, and improve development efficiency and work efficiency.
4. How to learn programming?
1. Learning the basic knowledge of language: including mastering the basic knowledge of programming language syntax, data types, variables, operators, loop statements, conditional statements, etc. It can be learned through tutorials for beginners, programming books, or online teaching platforms.
2. Practice programming: After learning a programming language, you need to practice writing programs, write small programs or refer to other open source programs to get started. Through this process, you can better deepen your understanding and mastery of programming languages.
3. Learn programming concepts, patterns, and tools: Learning programming requires knowledge of related concepts such as object-oriented programming, programming patterns, and basic data structures. In this process, you need to use some development tools, such as programming editors, Git version controllers, debugging tools, and so on.
4. Read, analyze, understand, maintain, and debug open source code: Open source code is one of the very good reference materials when learning programming. By reading open source code, we can learn common programming patterns, development ideas and how to write efficient and stable code. At the same time, it is even more important to analyze the code, understand the implementation principle, and be familiar with commonly used debugging techniques and tools.
Finally, summarize the basic methods of learning programming:
1. Make a learning plan in advance and establish your own learning goals;
2. Learn and master basic programming knowledge;
3. Combine project practice, independently explore, write code, and debug;
4. Online learning community: read the Q&A in the community, Blogs, project codes, etc., to find valuable reference materials;
5. Maintain the continuity and speculative nature of learning, and improve your self-learning ability and problem-solving ability.Programming learning requires continuous learning, practice and precipitation in order to gradually grow into an excellent programmer.
5. How can beginners improve their programming skills
1. Write more code: Whether it is practice or project practice, you need to write code continuously, debug and optimize continuously, which is the basis for improving programming ability.
2. Read excellent open source code: Reading other programmers' code can learn their programming skills and experience, and improve your programming ability and code quality.
3. Learning data structures and algorithms: Data structures and algorithms are the foundation of computer science. Learning and mastering them can help novice programmers better understand and write efficient code.
4. Keep learning new technologies: Programming technology is constantly developing and upgrading. Good programmers need to keep up with the pace of technology, actively learn new technologies, and expand their skills.
5. Read related books and materials: During the learning process, you can read related books and materials to get more comprehensive and in-depth knowledge, and at the same time avoid blind learning and wasting time.
6. Participate in programming communities and activities: By entering the programming community, you can meet more programmers, exchange experience and ideas, and at the same time participate in some programming competitions to exercise and improve your programming skills.
7. Summarize and share programming experience: In the process of writing code, constantly summarize and share your own learning experience, and let others evaluate your code, which will make your program more perfect, and will also further improve your own programming ability improvement.
In short, improving programming ability requires continuous learning and practice, overcoming difficulties and challenges, and improving your programming level in various ways. I believe that through continuous efforts, you will become an increasingly excellent programmer.
