From the moment you start learning programming , It's destined to be the way to go in the future — Starting with programming learners , Experience interns in turn 、 The programmer 、 Software engineer 、 Architects 、CTO And so on ; When you stand at the top of your position and suddenly look back , You will find that your success is not accidental , In the growth of programmers, there will be constant code modification 、 Find and solve Bug、 The experience of constantly testing programs and modifying projects .
There is no denying that , As long as you are steady in your development career , And good at summarizing and learning , In the end, there will be a gratifying harvest .
Get into 2018 After year , More and more people around me say Python Language is at its zenith , Others say Python The speed of development is like sitting on a rocket . Exactly? Python What is the magic of language , So that the vast number of programmers are infatuated with it ？
This article will introduce in detail Python The development and characteristics of language , Find the answers to the above questions with the readers .
Once a hit show 《 List of reed {langya} 》 There are clouds. ： It's like ice and snow in the world , The hidden fragrance floating in the river , Know all the heroes in the world , Bow to Jiang Zuo you meilang …… The Langya list is similar to the list of experts in martial arts novels .
In fact, it has its own programming language “ List of reed {langya} ”, This is it. TIOBE Programming language community rankings , The list will be updated monthly , The ranking of the list objectively and fairly shows the status of each programming language .
TIOBE The programming language community rankings use the famous search engine （ Such as Google、MSN、Yahoo!、Wikipedia、YouTube as well as Baidu etc. ） Calculate , stay 2017 In the first half of ,Java Language and C Language is still the biggest winner . In fact, in the list of recent years , Programmers are used to C Language and Java Of “ Song and dance duet ” The situation .
Believe in TIOBE The ranking in the programming language community rankings will surprise many readers ,Python Language is in the first place PHP、JavaScript And so on . It doesn't seem reasonable , Because few people mentioned it in my impression Python, On the contrary, I often hear people talk about C、C++、Java、C# and PHP,Python Why is language so popular ？ The author thinks Python The reason why language is so popular , There are two main reasons .
（1） Simple
Whether it's for learners or programmers , Simplicity has the greatest attraction . Since we can all achieve the same function , Why don't people choose a simpler development language ？ for example , Running Python The program , Just simply type in Python The code is ready to run , It doesn't need to be like other languages （ for example C or C++） That requires intermediate steps such as compilation and linking .
Python The program can be executed immediately , This creates an interactive programming experience and the ability to quickly adjust in different situations , Often after modifying the code, you can see the effect of the program immediately .
（2） Powerful
Python Language can be used as a batch language , Write some simple tools , Processing some data , As the interface debugging of other software .
Python Language can be used as a functional language , Developing artificial intelligence programs , have Lisp Most of the functions of language .
Python Language can be used as a process language , Common application development , You can talk to VB And so on .
Python Language can be used as an object-oriented language , Has most of the characteristics of an object-oriented language , It is often used as a prototype development language for large-scale application software , And then use C++ Language rewriting , And some applications use it directly Python To develop .
In addition to the simple and powerful features described in the previous section ,Python Language also has the following characteristics .
（1） object-oriented
Python It's object-oriented programming （ Object oriented programming is abbreviated as “OOP”） Language , Its class module supports polymorphism 、 Advanced concepts such as operator overloading and multiple inheritance , And take Python Unique and concise syntax and types , Object oriented is very easy to use .
In addition to being a powerful tool for code building and reuse ,Python The object-oriented features of make it an object-oriented language （ Such as C++ and Java） The ideal scripting tool for . for example , By pasting the code properly ,Python The program can be used to C++、Java and C# Class for subclass customization .
（2） free
Python It's completely free to use and distribute , Just like other open source software , Such as Perl、Linux and Apache. Developers can start from Internet Free access Python Source code . Copy Python, There's no limit to embedding it in your system or releasing it with the product .
（3） portable
Python The standard implementation of the language is made up of portable ANSI C Compiling , It can be compiled and run on all the current mainstream platforms . Now from PDA To supercomputers , You can see it everywhere Python Program operation .Python The language can run on the following platforms （ Be careful , That's not all , But only a part of what I know ）.
Linux and UNIX System .
Microsoft Windows.
Mac OS（ Include OS X and Classic）.
BeOS、OS/2、VMS and QNX.
Real-time operating system , for example VxWorks.
Cray Supercomputers and IBM The mainframe .
function Palm OS、PocketPC and Linux Of PDA.
Game terminal .
（4） Hybrid development
Python Programs can be easily integrated with components written in other languages in many ways . for example , By using Python Of C Language API Can help Python The program flexibly calls C Program . This means that you can give as much as you need Python Program add function , Or in other environmental systems Python.
for example , take Python And C perhaps C++ The library files are mixed together , send Python Become a front-end language and customization tool , This makes Python Become a good rapid prototyping tool . For the sake of development speed , The system can be used first Python Realization , Then move to C, In this way, the system can be implemented step by step according to the performance requirements of different periods .
Learn from good examples Python Whether it's employment or sideline, it's good to make money , But learn to Python Still have a learning plan . Finally, let's share a complete set of Python Learning materials , For those who want to learn Python Let's have a little help ！
Python The technical points in all directions are sorted out , Form a summary of knowledge points in various fields , The use of it is , You can find the corresponding learning resources according to the above knowledge points , Make sure you learn more comprehensively .（ At the end of the article ！）
reminder ： Limited space , Packaged folder , The way to get it is “ At the end of the article ”！！！
Watch the zero basics learning video , Watching video learning is the quickest and most effective way , Follow the teacher's ideas in the video , From foundation to depth , It's still easy to get started .
Optical theory is useless , Learn to knock together , Do it , Can you apply what you have learned to practice , At this time, we can make some practical cases to learn .
Check the learning results .
We learn Python Must be to find a well paid job , The following interview questions are from Ali 、 tencent 、 The latest interview materials of big Internet companies such as byte , And the leader Ali gave an authoritative answer , After brushing this set of interview materials, I believe everyone can find a satisfactory job .
