[snippsat]

What version of python are you running?
If run stock() function alone do it return the result.

from bs4 import BeautifulSoup
import requests
import time

def stock():
    requestbtc = requests.get("https://bitscreener.com/coins/bitcoin")
    requestseth = requests.get("https://bitscreener.com/coins/ethereum")
    content1 = requestbtc.content
    content2 = requestseth.content
    soup1 = BeautifulSoup(content1,"html.parser")
    soup2 = BeautifulSoup(content2,"html.parser")

    element1 = soup1.find('div',{"class":"header-price-container"})
    btc = element1.text.strip().replace('\n',' \t ')
    element2 = soup2.find('div',{"class":"header-price-container"})
    eth = element2.text.strip().replace('\n',' \t ')
    return btc, eth

print(stock())

Output:
('$9,071.34 \t  \t  \t -$106.24\xa0 \t (-1.16%)', '$205.60 \t  \t  \t -$1.8007\xa0 \t (-0.87%)')

The error indicate that it return None,also same what BS return if do not find the tag.
Just to make the same error.

def stock():
    return None

>>> btc, eth = stock()
