Python Code Examples

Example 1: Flask Blog Application

        
from flask import Flask, render_template, request

app = Flask(__name__)

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

@app.route('/post', methods=['POST'])
def create_post():
    title = request.form['title']
    content = request.form['content']
    # Code to save title and content in database
    return redirect('/')

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

Example 2: Django To-Do List Application

        
from django.shortcuts import render, redirect
from .models import Task

def task_list(request):
    tasks = Task.objects.all()
    return render(request, 'task_list.html', {'tasks': tasks})

def add_task(request):
    if request.method == 'POST':
        new_task = Task(description=request.POST['description'])
        new_task.save()
        return redirect('task_list')
    return render(request, 'add_task.html')
        
    

Example 3: FastAPI RESTful API Development

        
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

class Item(BaseModel):
    name: str
    price: float

@app.post("/items/")
def create_item(item: Item):
    return {"name": item.name, "price": item.price}

if __name__ == '__main__':
    import uvicorn
    uvicorn.run(app, host="127.0.0.1", port=8000)
