Получаю ошибку при запуске скрипта

IDLE (Python 3.10 64-bit)
Windows 10
---------------------------
Есть такой скрипт:

# coding: utf8
# == pars_playlist.py
# == select short information from Yotube playlist -- 
from urllib.request import urlopen
from BeautifulSoup import BeautifulSoup

print()
"pars_playlist working..."

# == get first linkof playlist ==
url = input('input link:')
url = "https://www.youtube.com/playlist?list=PLku9se_HAVOrs3p_jJzZAbV3BEODrhS3j"

fh = open('data.txt', 'w')

cur_num = 1  # index of reading page
try:
    while True:
        # -- get curent page --
        print()
        cur_num
        print()
        url
        content = urlopen(url)
        page = content.read()

        # -- cut head
        soup = BeautifulSoup(page)
        body = soup.find('body')

        # get current title
        span = body.find(id="ecw-title")
        title = span.getText()
        print()
        title

        # get list of all links
        ol = body.find(id="playlist-autoscroll-list")
        lis = ol.findAll('li')

        # soup for current page
        for idx, li in enumerate(lis):  # seek for picture
            li_title = li["data-video-title"]
            if li_title == title: break
        video_id = li["data-video-id"]

        # get picture information
        img = li.find('img')
        img_src = img['src']
        pos = img_src.find('?')
        if pos > 0: img_src = img_src[:pos]

        # get description of page
        descr = body.find(id="eow-description")
        descr_text = descr.getText()

        # save information
        fh.write(title.encode('utf8') + '\n')
        fh.write(video_id.encode('utf8') + '\n')
        fh.write(img_src.encode('utf8') + '\n')
        fh.write(descr_text.encode('utf8') + '\n')
        fh.write('\n')

        if idx >= len(lis) - 1: break

        # get next url
        idx += 1
        li = lis[idx]
        anc = li.find('a')
        href = anc['href']
        url = "https://www.youtube.com" + href

        cur_num = cur_num + 1

    # == 05 end of work ==
except:
    print()
    "exception: " + str(cur_num)
    pass
finally:
    fh.close()
    print()
    "ok"

Выдаёт ошибку:
File "E:\__Мои скрипты\1_test\parser_yotube.py", line 5, in <module>
from BeautifulSoup import BeautifulSoup
ModuleNotFoundError: No module named 'BeautifulSoup'

-------------------------------------------------
Пытаюсь установить модуль, опять ошибка:

[ForenLi]

Как устанавливаете? pip install beautifulsoup4 ?

[satfan]

Так
C:\Python\python.exe -m pip install BeautifulSoup
и так
C:\Python\python.exe -m pip install --upgrade beautifulsoup

[ForenLi]

beautifulsoup это старая bs3 версия, оставшаяся т.к. еще используют

[satfan]

Пробую так:
C:\Windows\System32>C:\Python\pytho n.exe -m pip install bs4
Requirement already satisfied: bs4 in c:\python\lib\site-packages (0.0.1)
Requirement already satisfied: beautifulsoup4 in c:\python\lib\site-packages (from bs4) (4.10.0)
Requirement already satisfied: soupsieve>1.2 in c:\python\lib\site-packages (from beautifulsoup4->bs4) (2.3.1)

[satfan]

Потом опять ошибка:
File "E:\__Мои скрипты\1_test\parser_yotube.py", line 5, in <module>
from BeautifulSoup import BeautifulSoup
ModuleNotFoundError: No module named 'BeautifulSoup'

Process finished with exit code 1

[ForenLi]

поправьте

from bs4 import BeautifulSoup

[satfan]

Спасибо.
Ошибка пропала.
Теперь просит:
input link:
В коде ссылка рабочая. Что не так ?

[ForenLi]

так уберите ввод

url = input('input link:')

раз захардкодили

[satfan]

Убрал эту строку: url = input('input link:')
Сработало без ошибок, но в файл: data.txt
Ничего не записалось.

Такой ответ:
The code that caused this warning is on line 27 of the file E:\__Мои скрипты\1_test\parser_yotube.py. To get rid of this warning, pass the additional argument 'features="html5lib"' to the BeautifulSoup constructor.

soup = BeautifulSoup(page)
