How do I fix "none" during Python web-scraping?

I am extremely new to python and webscraping, but I am trying to create a code where it pulls the prices of a CSGO Steam skin off of the steam website. It does constantly update, so I'm not sure what the issue is. I keep getting "None" as the output in console. I am using repl.it for my code. This is the code.

import requests
from bs4 import BeautifulSoup

URLChallengerCapsule = 'https://steamcommunity.com/market/listings/730/2020%20RMR%20Challengers'
page = requests.get(URLChallengerCapsule)
soup = BeautifulSoup(page.content, 'html.parser')
results = soup.find(id='market_commodity_buyrequests')

ChallengerCapsulePrice = results.find('span', class_= 'market_commodity_orders_header_promote')

print(ChallengerCapsulePrice)

Specifically, I am looking to solutions to this "none" issue AND any tips on my actual code would be much appreciated. Thanks.

What I have tried:

I've tried many small things like changing the link, trying with and without the "id" line.

Solution 1

It prints "None" because results.find('span', class_= 'market_commodity_orders_header_promote') does not find anything.

If you look at the html code in the link, you would've found that the price there does indeed include span, class, and market_commodity_orders_header_promote. So no, it is there.

Well that does not alter the fact that your code is not finding it. You should use the debugger and see exactly what happens at each step.

What is a debugger?

Something you need to learn: pdb — The Python Debugger — Python 3.7.9 documentation[^].
