Extracting Content Within Multiple Span Tags in BeautifulSoup

I'm trying to extract string content from and within multiple span tags. A snap shot of the HTML page is:

<div class="secondary-attributes"> <span class="neighborhood-str-list"> Southeast </span> <address> 1234 Python Blvd S<br>Somewhere, NV 98765 </address> <span class="biz-phone"> (555) 123-4567 </span> </div> 

Specifically, I'm trying to extract the phone number, nestled in between the <span class="biz-phone></span> tags. I attempted to do so with the following code:

import requests from bs4 import BeautifulSoup res = requests.get(url) soup = BeautifulSoup(res.text, "html.parser") phone_number_results = [phone_numbers for phone_numbers in soup.find_all('span','biz-phone')] 

The code compiled without any syntax errors, but it didn't quite give me the result I was hoping for:

['<span class="biz-phone">\n (702) 476-5050\n </span>', '<span class="biz-phone">\n (702) 253-7296\n </span>', '< span class="biz-phone">\n (702) 385-7912\n </span>', '<span class="biz-phone">\n (702) 776-7061\n </span>', '<spa n class="biz-phone">\n (702) 221-7296\n </span>', '<span class="biz-phone">\n (702) 252-7296\n </span>', '<span c lass="biz-phone">\n (702) 659-9101\n </span>', '<span class="biz-phone">\n (702) 355-9445\n </span>', '<span clas s="biz-phone">\n (702) 396-3333\n </span>', '<span class="biz-phone">\n (702) 643-9851\n </span>', '<span class=" biz-phone">\n (702) 222-1441\n </span>'] 

My question has two parts:

1. Why are the span tags appearing when I run the program?
2. How do I get rid of them? I could just do string editing, but I feel like I wouldn't be taking full advantage of the BeautifulSoup package. Is there a more elegant way?

NOTE: there are more snippets of HTML code like the one shown above throughout the page; there are more instances of the <span class="biz-phone"> (555) 123-4567 </span> code (i.e., more phone numbers) that need to be extracted, hence why I was thinking of using find_all().

Thank you in advance.
