from bs4 import BeautifulSoup

html = """
<html><head></head>
<body>
<h2 class='title'><a href='http://www.mypage.com'>My HomePage</a></h2>
<h2 class='title'><a href='http://www.mypage.com/sections'>Sections</a></h2>
</body>
</html>
"""
#you can use your intended webpage by reading the webpage as:
#with open("index.html") as fp:
#   soup = BeautifulSoup(fp, 'html.parser')

soup = BeautifulSoup(html, 'html.parser')

def extractUrlText():
    url = soup.find('a', href=True)['href']
    urlText = soup.find('a', text=True).get_text(strip=True)
    return (url, urlText)

print(extractUrlText())

Use the extractUrlText() function to achieve the required result.

Sample Output:
