Python Code Examples

            
# Example code for a simple Flask To-Do List app
from flask import Flask, render_template, request, redirect

app = Flask(__name__)

tasks = []

@app.route("/")
def index():
    return render_template("index.html", tasks=tasks)

@app.route("/add", methods=["POST"])
def add():
    task = request.form.get("task")
    if task:
        tasks.append(task)
    return redirect("/")

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

            
# Example code for a RESTful API with Django REST Framework
from rest_framework import serializers, viewsets
from .models import Book

class BookSerializer(serializers.ModelSerializer):
    class Meta:
        model = Book
        fields = '__all__'

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