Getting Started with Python Web Development
Steps to Begin
- Install Python: Download Python from the official website and follow the installation instructions.
- Choose a Framework: Assess project requirements and select a framework such as Django, Flask, or Pyramid.
- Set Up a Development Environment: Create a project folder and set up a virtual environment using `venv` or `virtualenv`.
- Install Framework and Dependencies: Use `pip` to install your chosen framework and any required packages.
- Initialize Your Project: Use framework commands to create the project structure (e.g., `django-admin startproject projectname` for Django).
- Configure Settings: Modify configuration files to set up databases, URLs, and security options.
- Define Models: Create data models that represent your application’s data structure.
- Create Views and Templates: Implement views for handling requests and render templates for displaying content.
- Define URL Routes: Map URLs to specific views to handle user requests efficiently.
- Handle Forms and User Input: Enable user interaction through forms, managing input using forms and APIs.
Popular Python Web Development Frameworks
- Django: A high-level framework that promotes rapid development and clean, pragmatic design.
- Flask: A lightweight micro-framework that is easy to learn and flexible for small to medium web applications.
- Pyramid: A flexible and modular framework suitable for both small and large applications.
- FastAPI: A modern framework for building APIs with Python, which is fast, easy to use, and promotes asynchronous operations.

app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/post', methods=['POST'])
def create_post():
# Logic for creating a post
title = request.form['title']
content = request.form['content']
# Save post to database...
return redirect(url_for('index'))
if __name__ == '__main__':
app.run(debug=True)
Task Management App Example in Django
from django.db import models
class Task(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
completed = models.BooleanField(default=False)
# views.py
