Beautiful Soup returning XX instead of actual values

Question

I am trying to Webscrape a website using requests and beautiful soup.

But I am getting 'XXX' instead of the text within the tags.

code:

url = 'https://www.discover.com/student-loans/'

req = opener.open(url)
data = req.read().decode('utf8')

from bs4 import BeautifulSoup

soup = BeautifulSoup(data,'html.parser')
rate_element = soup.find('div',class_='variableRate')
if rate_element :
        rate_Fixed = rate_element.get_text().strip()
        print("Interest rates:",rate_Fixed)
else:
        print('rate not found')
