Flask
Flask is a micro-framework known for its flexibility and minimalism, making it ideal for smaller projects.
- Key Features: Lightweight and customizable.
- Advantages: Easy to learn with high customization options.
- Disadvantages: Limited built-in features require manual setup for more complex functions.
Pyramid
A flexible framework also favored by industry leaders, Pyramid is designed for both small and large applications.
- Key Features: Flexibility and efficient URL routing.
- Advantages: Scalability and a measured quality in application development.
Getting Started with Python Web Development
- Install Python: Download and install Python from the official Python website.
- Choose a Web Framework: Depending on your project size, consider frameworks like Flask for smaller tasks or Django for complex applications. For more resources, check out this beginner’s guide.
- Set Up a Development Environment: Use virtual environments like `venv` or `virtualenv` to isolate project dependencies.
Best Practices for Python Web Development
- Maintain virtual environments to avoid package conflicts.
- Organize your code using consistent naming conventions and modular structures.
- Test your code regularly with tools like `unittest`.
- Employ a version control system like Git for better management.
- Deploy your application using platforms such as Heroku or AWS after thorough testing.

class Post(models.Model):
title = models.CharField(max_length=100)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
Example 3: RESTful API with Flask
from flask import Flask, jsonify, request
app = Flask(__name__)
books = []
@app.route('/api/books', methods=['POST'])
def add_book():
book = request.json
books.append(book)
return jsonify(book), 201
@app.route('/api/books', methods=['GET'])
def get_books():
return jsonify(books)
if __name__ == '__main__':
app.run(debug=True)
