Python Code Examples

            
# Example code for a simple Flask blog application
from flask import Flask, render_template, request, redirect

app = Flask(__name__)

posts = []

@app.route('/')
def home():
    return render_template('home.html', posts=posts)

@app.route('/add', methods=['POST'])
def add_post():
    title = request.form.get('title')
    content = request.form.get('content')
    posts.append({'title': title, 'content': content})
    return redirect('/')

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

            
        

            
# Example code for a simple Django RESTful API
from django.urls import path
from rest_framework import viewsets
from .models import Book
from .serializers import BookSerializer

class BookViewSet(viewsets.ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookSerializer

urlpatterns = [
    path('books/', BookViewSet.as_view({'get': 'list', 'post': 'create'})),
]
