Using the internet means you are using the web server every time you open a website or application. It works in the background to deliver the page you requested including a simple personal blog, social media platforms, or any other app/site.
Well, Python web servers have become a popular choice for web development. Python offers extensive tools to set up web servers efficiently.
In this blog, we will cover all basics related to – ‘What is Python web server?’ Know its key features and how you can create one yourself.
Learning about a Web Server is a great starting point towards becoming a Python expert. So, we will start there.
What is a Web Server?
A web server handles incoming requests from clients (browsers) and processes them to respond with the appropriate content. It works through the HTTP (Hypertext Transfer Protocol), which is used for web communication.
Web servers are designed to perform several functions:
- Handle client requests and responses.
- Deliver static content such as HTML, CSS, and images.
- Run server-side scripts that generate dynamic content.
- Ensure security through features like SSL/TLS encryption.
What is Python Web Server?
Now let’s move on to – What is a Python web server?
So basically a web server built using Python is a Python web server. Developers can create and host web applications in a flexible and easy-to-implement manner.
A Python Web Server can be created using various Python libraries such as http.server, Flask, Django, and more. The one built with the built-in Python HTTP Server module is the most basic one.
Key Features of Python Web Server
1. Easy to Setup and Use
A basic Python web server requires a simple setup. You can use the built-in Python SimpleHTTPServer Example as a beginner or for quick testing or local development. It requires minimal code. Also, it is best for serving static files such as HTML pages, images, and CSS files.
Scalability with Frameworks
You can get more advanced features using frameworks such as Flask or Django. They provide additional tools and functionalities for creating complex applications such as database support, form handling, authentication, and more.
Example:
- Django offers full-fledged functionality for developing production-ready websites. It has built-in tools for handling tasks like routing, templating, and database integration.
- Flask offers a minimalist approach. It gives you more flexibility but you need to build additional features as per your needs.
2. Flexibility and Customization
You can configure it to handle different types of content. Also, it can interact with databases and serve dynamic pages based on client requests.
- You get started with Python for a simple web server and enhance it as needed.
- You can integrate other technologies such as JavaScript, HTML5, or CSS to build interactive web applications.
3. Python Web Server Gateway Interface (WSGI)
One of the standout features is its ability to support the Python Web Server Gateway Interface (WSGI). WSGI is a standard for Python web servers to communicate with web applications. It is a specification that defines how web servers communicate with Python web applications. Thus, you can easily integrate with frameworks like Flask and Django.
It is a component required to deploy a Python web server in a production environment. Also, it ensures that your web applications are portable across different servers.
Moreover, WSGI acts as a middle layer. Its function is to translate web server requests into Python function calls and vice versa. As a result, developers can focus on the application logic and WSGI handles the server management
4. Built-in Development Server
The Python HTTP Server is a development server and it has Python’s standard library. It is ideal for beginner or temporary server testing. However, it is not meant for production use. It can quickly test your Python web apps.
- Easily set up a basic Python web server with http.server module. You do not need to install any external dependencies.
- It is not suitable for high-traffic production environments.
5. Other Features
- Support for multiple communication protocols such as HTTP, HTTPS, WebSockets, etc.
- You can flexibly define custom routes that map to different actions in your application.
- You can implement security features like SSL/TLS encryption for secure communication between the server and clients.
- They support various databases like MySQL, PostgreSQL, and MongoDB.
- They are relatively easy to deploy on cloud platforms or on your own infrastructure.
Benefits of Using Python for a Web Server
Let’s go through a few of its benefits too –
- Beginner-friendly – The code for setting up a Web Server Using Python is clean and easy to understand.
- Extensive Python Library – Python has a huge collection of libraries that can make the development process easier. You can quickly add functionalities such as form handling, authentication, and even database management with minimal effort. Libraries like Flask, Django, and FastAPI make it easy to build sophisticated web applications.
- Community – Python has a large and active community. You can easily find resources to help you build your web server. Various Python experts are always available to assist you.
- Compatibility – Python integrates well with all operating systems (Windows, Linux, and macOS). You can expect it to work seamlessly on different platforms.
- Versatility – Python is a multi-purpose language. It is used to set up web servers mainly. However, it also works with databases, file management, or even machine learning. Thus, you can build any type of web application.
- Cost-effective – Python is open-source so there are no licensing fees.
How to Create a Python Web Server?
Let’s go through the step-wise process of creating a web server using Python. You don’t need any special tools or frameworks for the same.
1. Create a Simple Python Web Server with just a few lines of code using Python’s Built-In HTTP Server
This server listens for incoming HTTP requests and serves the requested files. Refer the below steps to know how you can set it up (Python SimpleHTTPServer Example to convert a directory to simple HTTP web server)
- Open your terminal or command prompt. Then, go to the directory where your HTML files are stored. After that, run the below command –
python -m http.server 8000
- This command will start a server on port 8000. You can now open a browser and visit http://localhost:8000 to see the files being served.
This setup is perfect for testing and small projects. You don’t need to install any additional software because everything comes with the Python installation.
2. Using Python with Flask or Django For More Advanced Applications
Python experts prefer to use frameworks like Flask or Django. These frameworks provide more powerful features like routing, request handling, and database integration. Below are the steps –
1. Install Flask with the below command –
pip install Flask
2. Create a Python file (e.g., app.py) and define the server logic –
from flask import Flask
app = Flask(__name__)
@app.route(‘/’)
def home():
return “Best Cantech Hosting Solutions”
if __name__ == ‘__main__’:
app.run(debug=True)
This code will start a Python Web Server and show “Best Cantech Hosting Solutions” when you visit the home route.
3. Using Python Server Pages (PSP)
Python Server Pages (PSP) gives a more embedded approach to writing HTML and Python code together. That is, you can mix Python code and HTML in the same file. It is similar to PHP but you use Python.
PSP is not as commonly used as Flask or Django. However, it is a fun way to quickly prototype small web applications.
Advanced Python Web Server
You need to create a Python Web Server with more features for more complex applications. So, you can build custom servers by using frameworks like Flask or Django.
You can build dynamic web applications by handling HTTP requests, user sessions, and database interactions.
Also, when you use Python for a simple web server, you can even extend the basic capabilities with advanced routing, templates, and even RESTful APIs. These frameworks provide a lot of built-in functionalities for more professional-grade applications.
Python Web Server and Server-Side Scripting
Python can handle server-side scripting and this is one of the things that makes it unique from other languages. You can write scripts with Python Server Pages (PSP) that run on the server and generate dynamic content for users. Also, you can combine Python web server functionality with HTML templates to generate dynamic pages based on user input.
Further, Python-based frameworks like Django and Flask offer a more comprehensive environment for building dynamic web applications.
Conclusion
Python Web Server is a very powerful tool that can handle both basic and complex web tasks. You can serve static files or create dynamic web applications too. It makes it easy to get started as you don’t even need to be a Python expert.
