This article introduces you how to simply understand the introduction to pythonp-, the content is very detailed, interested friends can refer to, hope to be helpful to you.

A brief understanding of python

Python language features

1. Python is an interpretive language

Interpretive language: interpreters are required when running in the system (e.g. php, java)

Compiled language: you don't need an interpreter to run in the system, you can run it directly (e.g. C, C++)

two。 Weakly typed language

To put it simply, weakly typed languages can be used directly without declaring the types of variables in advance.

The strongly typed language must declare the type of the variable in advance, otherwise the variable cannot be used.

3. Object-oriented language

The Python language supports complete object-oriented programming, as well as procedural and functional programming. It can be understood that in python, everything is an object.

4. Glue language

Python can easily combine modules written in other languages (especially with c and C++). In addition, most of the python language itself and extension libraries are built by c language.

Python application field

Python has a wide range of applications:

Such as: web application development, automated operation and maintenance, web crawler, big data analysis, image processing, scientific computing, games, desktop software, artificial intelligence, etc.

At present, almost all large and medium-sized Internet enterprises in the industry are using python.

Such as: Youtube, Douban, Zhihu, Google, yahool, facebook, Baidu, Tencent, Meituan, etc.

At present, python has been firmly in the top three in the list of programming languages.

Advantages of Python

1. simple

Python is a language that represents the idea of simplicity.

Reading a good Python program is like reading English. Enables you to focus on solving problems rather than understanding the language itself.

two。 The Book of changes

Python is extremely easy to use because python has extremely simple documentation

3. High speed

Because python advocates elegance, clarity and simplicity, it implements the same function and uses much less code than other languages.

And because the bottom layer is written in c language, many standard libraries and third-party libraries are also written in c language, so it runs very fast.

4. Free, open source

Python is one of the floss.

Users are free to publish a copy of the software, read its source code, change it, and use part of it in new free software.

On how to simply understand the introduction to pythonp- to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
