foreword
The three major frameworks of Python are Django, Flask and Tornado. Below I will introduce their advantages, disadvantages and application occasions respectively.
Table of contents
1. Django
Django is a full-featured web framework, which provides many built-in functions, such as ORM, template engine, form processing, user authentication and so on. The advantages of Django are:
Advantage:
- Comes with ORM, you can easily operate the database.
- Built-in template engine, you can quickly build pages.
- With its own management background, it can quickly build a management system.
- An active community with a large number of third-party libraries and plugins.
- High security, built-in security mechanisms to prevent SQL injection and XSS attacks.
Disadvantages:
- The learning curve is relatively steep, and a certain basic knowledge of Python is required.
- Large amount of code, suitable for large projects.
- Relatively low performance, not suitable for high concurrency scenarios.
Applications:
- Suitable for large web applications, such as social networks, e-commerce platforms, etc.
- Suitable for applications that need to manage the background, such as blogs, news sites, etc.
2. Flask
Flask is a lightweight web framework, its design philosophy is simple, flexible, and easy to expand. The advantages of Flask are:
Advantage:
- High flexibility, you can freely choose plug-ins and libraries according to your needs.
- The learning curve is relatively gentle, suitable for beginners.
- The amount of code is small, suitable for small projects.
- High performance, suitable for high concurrency scenarios.
Disadvantages:
- Lack of built-in ORM and template engine, you need to choose a third-party library yourself.
- Lack of management background, you need to build it yourself.
- The security is low, you need to add a security mechanism yourself.
Applications:
- Suitable for small web applications, such as blogs, personal websites, etc.
- Suitable for applications that require high performance, such as API services, real-time communication, etc.
3. Tornado
Tornado is a high-performance web framework designed with asynchronous non-blocking I/O. The advantages of Tornado are:
Advantage:
- High performance, suitable for high concurrency scenarios.
- Asynchronous non-blocking I/O, which can handle a large number of concurrent requests.
- With WebSocket support, you can quickly build real-time communication applications.
- Can be combined with other asynchronous frameworks such as asyncio.
Disadvantages:
- The learning curve is steep, requiring knowledge of asynchronous programming.
- Lack of built-in ORM and template engine, you need to choose a third-party library yourself.
- Lack of management background, you need to build it yourself.
- The security is low, you need to add a security mechanism yourself.
Applications:
- Suitable for high concurrency scenarios, such as real-time communication, online games, etc.
- Suitable for applications that require high performance, such as API services, data processing, etc.
