Simple Blog Application using Django
# Install Django
# pip install django
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
RESTful API with Flask
# Install Flask
# pip install Flask
from flask import Flask, jsonify, request
app = Flask(__name__)
tasks = []
@app.route('/tasks', methods=['GET'])
def get_tasks():
return jsonify(tasks)
@app.route('/tasks', methods=['POST'])
def add_task():
task = request.json
tasks.append(task)
return jsonify(task), 201
Personal Portfolio Website using Flask
# Install Flask
# pip install Flask
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
return render_template('index.html')
if __name__ == '__main__':
app.run(debug=True)
Weather App using Django
# Install requests
# pip install requests
import requests
def get_weather(city):
api_key = 'your_api_key'
url = f'http://api.openweathermap.org/data/2.5/weather?q={city}&appid={api_key}'
response = requests.get(url)
return response.json()
