get function returns None from Beautifulsoup object

[DeanAseraf1]

I managed to fix the code. here is the new one:

import requests
from bs4 import BeautifulSoup


def spider(max_pages):
    page = 1
    while page <= max_pages:
        main_page = 'https://wikipedia.org/wiki/'
        search = input("Enter your search: ")
        page_to_search = main_page + str(search)
        source_code = requests.get(page_to_search)
        plain_text = source_code.text
        soup = BeautifulSoup(plain_text, features="html.parser")
        for menu in soup.findAll('span', class_='toctext'):
            print(menu.text)


spider(1)
