Python web application building ideas

Python has become one of the most popular modern programming languages. In fact, Python applications can be found in various fields, especially it has demonstrated excellent web application development capabilities. Web applications in Python are based on various web frameworks built on top of the Python language. These frameworks are the libraries that come with Python and third-party libraries.

Python's web framework makes Python programming easier in building web applications. Python's web framework provides tools that enable developers to focus more on application logic rather than framework details. Python's web framework provides easy-to-use routers and controllers, which allow developers to easily route requests to appropriate handlers. Many Python web frameworks also provide templating systems that separate style and content from the application.

In Python web application development, the most common web frameworks are Flask and Django. Flask is a lightweight web application framework built on the Werkzeug WSGI toolbox and Jinja2 template engine. The Flask framework is ideal for building small to medium-sized web applications and is highly scalable and flexible. The use of the Flask framework is very simple, and you can write a web application in the Flask framework with just a few lines of code.

Different from Flask, Django is a heavyweight web framework. Django provides many functions, which involve all aspects of web applications, such as validation, ORM, templates, management panels, etc. Django provides developers with a unified development environment, application structure, template system, static file process, ORM, etc. Although the learning curve of the Django framework is relatively steep, it provides very good scalability and code management tools, which can help web applications go online quickly.

In Python, the concept of building web applications is not limited to the use of frameworks. Python provides many database connectors and ORM frameworks, such as SQLAlchemy, Django ORM, Peewee ORM, etc. ORM framework makes database access easy. The ORM framework can convert data in the database into Python objects, and allows developers to use objects to access data instead of using SQL statements for data access.

Python also provides many tools that facilitate automated testing, deployment, and integration of web applications. Python’s UnitTest class makes it easy to write automated tests for web applications. Python's continuous integration tools, such as Jenkins, Travis, and CircleCI, can detect new code in version control and then run automated testing, code analysis, and code deployment. Python also has many deployment tools such as Fabric and Ansible for automating the deployment of web applications.

To sum up, Python’s web application construction concept is based on Python asynchronous, multi-threading and corresponding web frameworks. Python's web framework provides many out-of-the-box tools, making writing web applications easy and fast, and developers can focus more on the business logic of the application. Python's web framework also involves many other libraries and auxiliary tools, such as ORM tools, continuous integration and deployment tools, etc. These tools can further optimize the development, testing and deployment process of web applications.
