Python introduction to the correct posture is what, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

The correct posture for getting started with Python! Junior developers are easy to fall into a daze when learning Python. In the face of a wide variety of programming languages and frameworks on the market, it is important to stick to their own choices. This article is a guide article, an overview of the basis of programming, guidance, document reading, books and videos, source code and other learning and accumulation links, worthy of reference for beginners.

As a developer, why choose Python?

Why learn Python? Why choose Python over more than 20 other programming languages? When you start to become a developer, this question may come up in your mind many times a day.

Choosing your first programming language is like choosing an entry-level Pokemon.

If your goal is not Python, but other languages, you don't have to read on. If you are confident in your decision to choose Python, then this article will give you a higher chance of success. In fact, it doesn't matter which language you choose. But once you make a decision, you need to stick to it.

There are a large number of articles and viewpoints on the Internet that compare different programming languages / frameworks. These contents may make people feel at a loss as to what to do, or even scare some people to doubt their decision and give up halfway.

I know some people who claim to have mastered 3-4 languages. * * they want to know a lot about the details of the four languages, but they cannot program in any of them. * * this is the result of trying everything without sticking to it all the time.

Python is a well-designed language. There are a large number of online documentation and tutorials. And it is widely used in many fields. So, no matter how good you are, there's a lot to explore for Python. The same is true for most of the other 20 languages.

Each language has its own advantages and disadvantages, as well as the most suitable application field. The three most common uses of Python are data processing, writing Web application backends, and writing automation scripts. Python can be said to be the best choice for beginners, because the basic principles of this language design focus on clarity and simplicity.

How to learn Python?

Now that you have made your choice, let's talk about how to learn Python.

It's simple. Choose a tutorial and finish it. Then choose another tutorial. Take a break and repeat the process.

It is not possible to read only one book and watch a teaching video. You need constant access to code, gradual "overload" in your brain, patience, persistence, commitment (and other good qualities)!

The following is a basic flow chart for beginners. Different people have different versions of the roadmap. The following process is for reference only, but it is important to figure out when to move on to the next stage. Most people do it too late.

You may prefer to watch edX course videos rather than read books. Whatever it is, the most important thing is to stick to the whole process, which is more important than the choice of a single tutorial / course.

Build a solid foundation by reading books.

Refer to the Python-based tutorial on completing a single task, such as sending an email or writing a file. These tutorials introduce useful packages and libraries available to Python developers.

Get into the habit of reading documents. Build small applications using available libraries.

In-depth understanding of Python language and its tools. Understand the work being done by experts in this field.

Read the source code directly.

Remember, no matter what tutorial you take, make sure you're actually writing code all the time. It is not enough to just read the code examples.

Learn to solve general problems

There is a slight difference between learning a language (or framework / library) and learning programming

The full Stack Web developer course doesn't make you a good programmer. It will only teach you how to use a specific program to solve a simple problem (yes, most of the web applications built in these courses are indeed simple problems).

It's good to know and read programs, but it's even better to be able to design your own programs. Pay attention to the programming structure, design patterns and algorithms. These specific problems are not unique to Python, but are faced by almost all languages.

Looking for answers: from ignorance to omniscience

If you encounter difficulties many times in the process, try to solve the problem before you back down. It is quite possible that others have encountered the same problem before and have obtained a solution through the Internet.

There are many things worth learning in Python, which are widely used in various fields. Don't skip the basic knowledge stage and get busy entering a specific area of expertise. Learning PyTorch should be done after mastering packages and libraries, and learning Django should be familiar with virtual environments. In the long run, it is worth mastering in-depth knowledge of Python. When you use some special libraries, it is possible to greatly reduce the time spent debugging the program.

It takes time to learn things well. It may take longer than you think. You can't be an expert programmer in a few months. It takes time and energy to make progress. I suggest that beginners follow Python for at least one year. During this period, there will be distractions. Try to avoid distractions, but don't be afraid to learn and accept new things.

Python is not the only skill you need to be a comprehensive developer. Learning Git, Markdown, HTML and other knowledge can also be greatly rewarded. In the learning process, you may also need to master some JS or statistical information.

In short, always be a learner, but not just a learner!

Understand and practice the learning / practice phase cycle

The learning of any creative discipline can be divided into two stages, the learning stage and the construction stage, which are constantly repeated with each other.

During the learning phase, you should focus on accumulating knowledge, reading books, completing each tutorial, and exploring what has been done.

In the practical stage, you should be able to draw the conclusion of the previous stage by applying what knowledge has created. Don't doubt the skills you've learned and write your own applications. Only when you have completed this stage, go back and enter the learning stage.

Try to balance these two stages. First go through the study phase of one or two months, and then enter the construction phase of one month. Most people are afraid to enter the practical stage. Don't be afraid! Use what you have learned at this stage, and if it is really not enough, cycle through it a few more times.
