Python What to do ?Python You can do it web application development 、 Web crawler 、AI Artificial intelligence and machine learning 、 Process data for analysis 、 Data Science : Including machine learning 、 Data analysis and data visualization 、 Script and other aspects of development .

Python There are :

1、 do Web application development

In China, Douban is used from the beginning Python As web Develop basic languages , The whole structure of Zhihu is also based on Python Language , This makes web The development of this area is very good in China . The world's largest video website instagram Also use python Developed .

Did you learn Python People who don't know this library , The data analysis and calculation after crawling is Python The best field , It's very easy to integrate . But so far Python The popular web crawler framework is very powerful scrapy.

3、AI Artificial intelligence and machine learning

AI is very popular , All kinds of training classes are advertising to recruit students . machine learning , Especially now the hot deep learning , Most of its tool frameworks provide Python Interface .Python It has a good reputation in the field of scientific computing , Its concise and clear syntax and rich computing tools , It is loved by developers in this field .

Generally, we use reptiles to crawl to a large amount of data , Data needs to be processed for analysis , Otherwise, the reptiles will climb in vain , The ultimate goal is to analyze the data , In this regard The database of data analysis is also very rich , All kinds of graphic analysis charts, etc You can do it . It's also very convenient , Such as Seaborn Such a visual Library , Be able to plot data in just one or two lines , And the use of Pandas and numpy、scipy Then we can simply filter a large number of data 、 Regression, etc . In the subsequent complex calculation , Docking machine learning algorithms , Or offer Web Access interface , Or it is very simple to implement the remote call interface .

5、 Game development

Playing games often is very interesting , Have you ever thought about making a game for others ?Pygame Just a good one Python library , The cool thing about this library is that it's free and open source Python Language library , Games developed with it can run on almost all common operating systems .

Have they , Whether you're developing a website or not , Let's talk about corporate websites ,Python They are all competent for .

Website back end programmer : Use Python Single website , Background services are easier to maintain ; Automatic operation and maintenance : Automate a lot of O & M tasks ; Data Analyst : Rapid development, rapid verification , Analyze the data to get the results ; automated testing : Write as a simple implementation script , Apply to Selenium/lr in , Automation ; Website development : With the help of django,flask Frame your own website .
