Python Code Examples

Flask Personal Portfolio Example

            
from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def home():
    return render_template('portfolio.html')

if __name__ == '__main__':
    app.run(debug=True)
            
        

Django E-commerce Example

            
# settings.py
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'shop',
]

# views.py in "shop" app
from django.shortcuts import render

def product_list(request):
    return render(request, 'shop/product_list.html')
            
        

Real-World Applications

Python web development is widely used in various sectors:

• Social Media Platforms: Applications like Instagram leverage Django for its flexibility and scalability requirements.
• Content Management Systems: Many blogging platforms are built with Flask or Django due to their ease of use and rapid development capabilities.
• Data-Driven Websites: Websites requiring data manipulation and real-time results often utilize Python with frameworks that support asynchronous programming, such as Tornado.
