Instead of uploading data, an empty list?

Question

Python

Good afternoon!

For the first time I work with parsing and faced such an unpleasant problem - an empty list.
Googled and realized that the problem is frequent, but no solution at the moment has helped.
Every time it comes out or empty, for the life of me
I want to display for verification all the information with the class that appears in all blocks.

I'm due in a few hours, so I'll be glad for quick answers))

import requests 
from bs4 import BeautifulSoup
from bs4.builder._htmlparser import HTMLParserTreeBuilder





URL = 'https://www.vedomosti.ru/rubrics/finance/markets'

def get_html(url, params=None):
    r = requests.get(url, headers=HEADERS, params=params)
    return r
    
def get_content(html):
  soup = BeautifulSoup(html, 'html.parser')
  items = soup.find_all('a', class_='article-preview-item')
  
  print(items)


def parse():
    html = get_html(URL)
    if html.status_code == 200:
    	get_content(html.text)
    else:
        print('Error')
    

parse()
