How to find the number of occurrences of a word in the text of a web page using Python 3?

Question

Python

The task is described in the question. I have been looking for an hour on the Internet for something and how, but it seems that there is no progress. Tell me what functions to use, put me on the right path, so to speak))

Answer 1

And what is the actual problem? Well, at least like this:
text.count(word)

Answer 2

from collections import Counter
import re

from lxml.html import fromstring
from lxml.html.clean import Cleaner
import requests


def extract_text(node):
    """
    Extract text without markup from node
    """

    def extract_text_gen(node):
        if node.text:
            yield node.text.strip()
        for child in node.iterchildren():
            yield from extract_text_gen(child)
            if child.tail:
                yield child.tail.strip()

    return ' '.join((s for s in extract_text_gen(node) if s))


def count_words(text):
    return Counter((s for s in re.split(r'\s', text) if s))


html = requests.get('https://toster.ru/q/276749').content.decode('utf-8')
root = fromstring(html)
Cleaner()(root)
text = extract_text(root.body)
words_count = count_words(extract_text(root))

print('\n'.join(('"%s": %i' % (word, count) for word, count in words_count.most_common())))

The function extract_textis taken from one of my projects, slightly adapted and simplified.
