How to scrape yahoo finance news headers with BeautifulSoup?

I would like to scrape news from yahoo's finance, for a pair.

How does bs4's find() or find_all() work?

for this example:

with this link:

I'm traying to extract the data ... but no data is scraped. why? what's wrong?

I'm using this, but nothing is printed (except the tickers)

html = BeautifulSoup(source_s, "html.parser")  # "html")
            
            news_table_s = html.find_all("div",{"class":"Py(14px) Pos(r)"})
            
            news_tables_s[ticker_s] = news_table_s
        print("news_tables", news_tables_s)

I would like to extract the headers from a yahoo finance web page.

You have to iterate your ResultSet to get anything out.

for e in html.find_all("div",{"class":"Py(14px) Pos(r)"}):
    print(e.h3.text)

Recommendation - Do not use dynamic classes to select elements use more static ids or HTML structure, here selected via css selector

for e in html.select(' div:has(>h3>a)'):
        print(e.h3.text)

Example

from bs4 import BeautifulSoup
import requests

url='https://finance.yahoo.com/quote/EURUSD%3DX?p=EURUSD%3DX'

html = BeautifulSoup(requests.get(url).text)
            
for e in html.select(' div:has(>h3>a)'):
    print(e.h3.text)
