Python Code Examples
Personal Blog Application (Flask)
from flask import Flask, render_template, request, redirect
app = Flask(__name__)
@app.route('/')
def home():
return render_template('home.html')
@app.route('/post', methods=['POST'])
def add_post():
# Logic to add a post
return redirect('/')
if __name__ == "__main__":
app.run(debug=True)
To-Do List Web App (Flask)
from flask import Flask, request, redirect, render_template
todo_list = []
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html', todos=todo_list)
@app.route('/add', methods=['POST'])
def add_todo():
todo_item = request.form['todo']
todo_list.append(todo_item)
return redirect('/')
if __name__ == "__main__":
app.run(debug=True)
RESTful API Service (Django)
from rest_framework import viewsets
from .models import Item
from .serializers import ItemSerializer
class ItemViewSet(viewsets.ModelViewSet):
queryset = Item.objects.all()
serializer_class = ItemSerializer
Real-World Applications
Python web development has numerous real-world applications across various industries. Some significant examples include:
- Content Management Systems (CMS): Frameworks such as Django are widely used to build powerful CMS for handling websites efficiently.
