# news-retriever
|
||
|
||
To retrieve mathematics-related news using Python, we typically scrape trusted sources. Here are some examples.
|
||
|
||
## Method 1: Use Google News RSS
|
||
|
||
For example, we can fetch math-related news via RSS:
|
||
|
||
```
|
||
import requests
|
||
import xml.etree.ElementTree as ET
|
||
|
||
rss_url = "https://news.google.com/rss/search?q=mathematics"
|
||
|
||
response = requests.get(rss_url)
|
||
root = ET.fromstring(response.content)
|
||
|
||
for item in root.findall(".//item")[:5]:
|
||
title = item.find("title").text
|
||
link = item.find("link").text
|
||
print("Title:", title)
|
||
print("Link:", link)
|
||
print("-" * 40)
|
||
```
|
||
|
||
Running this code gives:
|
||
|
||
```
|
||
$ python3 example1.py

|
||
## Method 2: Use Python Libraries
|
||
Install feedparser (for RSS feeds):
|
||
|
||
```
|
||
$ python3 -m venv news-retriever
|
||
$ source news-retriever/bin/activate
|
||
$ pip install feedparser
|
||
```
|
||
|
||
Example with feedparser:
|
||
|
||
```
|
||
import feedparser
|
||
|
||
feed = feedparser.parse("https://news.google.com/rss/search?q=mathematics")
|
||
|
||
for entry in feed.entries[:5]:
|
||
print(entry.title)
|
||
print(entry.link)
|
||
print("-" * 40)
|
||
```
|
||
|
||
Running this code gives:
|
||
|
||
```
|
||
$ python example2.py

## Tips for Better Results
|
||
1. Use keywords like:
|
||
- "pure mathematics"
|
||
- "applied math"
|
||
- "math research"
|
||
- "number theory breakthrough"
|
||
2. Filter by date or source for relevance.
|
||
3. Combine with scheduling (e.g., cron job) to automate daily updates.
