15 – Real-World Python Projects – News Aggregator

🎯 Project Objective

To build a News Aggregator Application that automatically fetches and displays the latest news headlines from multiple online sources using APIs or web scraping.

Skills Demonstrated:

• Working with APIs (requests, json)
• Parsing and structuring data
• GUI creation using Tkinter
• File handling and optional CSV export
• Error handling and API rate-limit management

---

🧠 Project Overview

The News Aggregator App allows users to:

• Fetch top news headlines from multiple sources (e.g., BBC, CNN, TechCrunch, etc.)
• Filter news by category (Technology, Business, Sports, Entertainment)
• Display results in a clean, scrollable GUI
• Optionally save news summaries to a file for later reading

Real-Life Applications:

• Personalized news dashboard
• Daily summary emailer
• Stock/crypto news monitor
• AI summarizer or alert system backend

🧩 Example Code – News Aggregator (Tkinter + NewsAPI)

Note: This script auto-installs missing modules.

import os
import sys
import subprocess

# ✅ Auto-install missing packages
def install(package):
    try:
        __import__(package)
    except ImportError:
        subprocess.check_call([sys.executable, "-m", "pip", "install", package])

install("requests")
install("tkinter")

import requests
import tkinter as tk
from tkinter import messagebox, scrolledtext
from datetime import datetime

# Replace with your free API key from https://newsapi.org/
API_KEY = "your_api_key_here"

def fetch_news(category="general"):
    url = f"https://newsapi.org/v2/top-headlines?country=us&category={category}&apiKey={API_KEY}"
    try:
        response = requests.get(url)
        data = response.json()

        if data["status"] != "ok":
            messagebox.showerror("Error", "Failed to fetch news.")
            return

        news_box.delete(1.0, tk.END)  # Clear previous text
        for article in data["articles"][:10]:  # Show top 10
            title = article["title"]
            source = article["source"]["name"]
            url = article["url"]
            description = article["description"]
            news_box.insert(tk.END, f"🗞️ {title}\n📍 Source: {source}\n🔗 {url}\n📝 {description}\n\n")
        news_box.insert(tk.END, f"Last updated: {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}\n")

    except Exception as e:
        messagebox.showerror("Error", f"Could not retrieve news: {e}")

# GUI setup
root = tk.Tk()
root.title("📰 News Aggregator App")
root.geometry("600x500")
root.config(bg="#f0f0f0")

tk.Label(root, text="Select News Category:", font=("Arial", 12, "bold"), bg="#f0f0f0").pack(pady=10)

categories = ["general", "business", "technology", "sports", "entertainment", "science", "health"]
category_var = tk.StringVar(value="general")
category_menu = tk.OptionMenu(root, category_var, *categories)
category_menu.pack()

tk.Button(root, text="Fetch News", command=lambda: fetch_news(category_var.get()),
          font=("Arial", 12), bg="#2196F3", fg="white").pack(pady=10)

news_box = scrolledtext.ScrolledText(root, wrap=tk.WORD, width=70, height=20, font=("Arial", 10))
news_box.pack(padx=10, pady=10)

root.mainloop()

🔧 How It Works

1. User selects a category (e.g., “technology”).
2. App calls NewsAPI with the selected parameter.
3. JSON response contains headline data.
4. GUI displays the top stories with titles, sources, and URLs.

---

🌍 API Setup

1. Visit https://newsapi.org/
2. Sign up and generate a free API key
3. Replace: API_KEY = "your_api_key_here"
4. Run the script — your news app goes live! 🚀

---

💾 Optional – Export Headlines

Add this snippet after fetch_news() to save results to a file:

with open("latest_news.txt", "w", encoding="utf-8") as file:
    for article in data["articles"]:
        file.write(f"{article['title']} - {article['source']['name']}\n")

✅ You can later upgrade it to export CSV or Excel using pandas.
