This article mainly introduces "what are the main contents of Python". In daily operation, I believe many people have doubts about the main contents of Python. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the main contents of Python?" Next, please follow the editor to study!

The main body of Python can be divided into the following parts:

Process-oriented. Including basic expressions, if statements, loops, functions, etc. If you have a foundation for any language, especially C, this part is to learn about Python rules minute by minute. If you do not have a language foundation, it is recommended to use Python Programming as a reference book. This book is an introduction to computers and does not require a programming foundation.

Object-oriented, including object-oriented basic concepts, classes, methods, properties, inheritance and so on. Python is an object-oriented language, "everything is an object". Object-oriented is hard to avoid. The object-oriented mechanism of Python is relatively loose and not as strict as Java and C++. The advantages are easy to learn, easy to maintain, and the disadvantages are easy to make mistakes.

Application functions, including IO, data containers such as tables and dictionaries, built-in functions, modules, format strings, etc. These also appear frequently in other languages and have strong practicability.

Advanced syntax, context manager, list derivation, functional programming, decorators, special methods, etc. These grammars are not necessary, you can use the previous relatively basic syntax to implement. The main reason for learning these advanced grammar is that they are too convenient. For example, it takes several lines to derive a list of things that can be done with a loop structure.

The best reference book for learning Python subjects is Learning Python, which is very comprehensive and full of practical information. Although it is thick, it is not difficult to read. The other is to refer to the tutorial Python.org on the official website.

Python is known as "Battery Included", that is, functions are already included in the language. This confidence mainly comes from Python's fully functional standard library. The standard library provides many functional modules, each of which is the interface of a certain function, such as file management, operating system interaction, character processing, network interface, coding encryption and so on.

In The Python Standard Library, you can see a list of standard library modules. This is also the best learning material for the standard library. If you are looking for a book, I have only seen two books about the standard library:

Python Essential Reference

The Python Standard Library by Example

To be honest, these two books are not very good standard library teaching materials, and the reference books of the standard library are really difficult to write. Because the standard library is only an interface for invoking functions, the final realization is the interaction between Python and the system. This requires strong system knowledge, such as file system knowledge, process management, http principles, socket programming, database principles. If this knowledge is well prepared, then the standard library is not difficult to learn at all. However, the learning curve of these background knowledge is much steeper than Python itself.

The same is true for more in-depth Python learning, which requires a lot of background knowledge, not just Python itself. If you are interested in the extensibility of Python, you can try mixed programming as much as possible. If you are interested in how Python compiles and runs, you can dig into the bottom layer of Python to see how the compiler does it. If you are interested in applications, you can learn more third-party packages that you can use. To learn at this time, the spell is the realm, there is no law. There is a vast space for exploration.

Basically, after learning the main content, Python still has to practice by doing projects. There are a lot of materials of small exercise types, such as Python Cookbook. But a better way is to think of some application scenarios and use Python to solve them. For example:

Build a website

Be a web crawler

System management

Python is full-featured, so don't worry about the problems you think Python can't solve (basically problems that Python can't solve, not in other languages). For example, I learn the power of multithreading because I have to download a large number of files in parallel. Basically, several pieces of Python will be used in a project, and the knowledge will be particularly consolidated.

At this point, the study of "what are the main contents of Python" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
