Get YouTube Playlist urls with python

Thank you!
Here some dirty code working for me:

#--------------------------------- 
# import modules
from bs4 import BeautifulSoup as bs
from selenium import webdriver
import time
import re

#---------------------------------
#     
from webdriver_manager.firefox import GeckoDriverManager
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())

#---------------------------------
# get links from url    
def get_links(driver, sleep_time):

    # open driver window
    driver.set_window_size(1024, 600)
    driver.maximize_window()
    driver.get(url)    
            
    # wait some seconds
    time.sleep(sleep_time)
            
    # get information from url
    soup = bs(driver.page_source,'html.parser')
    res = soup.find_all('ytd-playlist-panel-video-renderer')  
            
    # check if there is information
    if len(res) > 0:
        main_url = 'https://www.youtube.com/watch?v='
        urls = re.findall('watch.*list', str(res))
        links = [main_url + str(a[8:-9]) for a in urls[::2]]
    # if there is no information return false
    else:
        links = False    
    return links

#---------------------------------
# set sleep timer
sleep_time = 10
# call function to get links
links = get_links(driver, sleep_time)

This works for me:

from selenium import webdriver  # pip install selenium
import time

# make sure you download chrome driver from https://chromedriver.chromium.org/downloads and put it in folder 'driver'
driver = webdriver.Chrome('driverchromedriver.exe')
driver.get('https://www.youtube.com/playlist?list=PLxvodScTx2RtAOoajGSu6ad4p8P8uXKQk')  # put here your link

# scroll page down
old_position = 0
new_position = None
position_script = """return (window.pageYOffset !== undefined) ?
          window.pageYOffset : (document.documentElement ||
          document.body.parentNode || document.body);"""
while new_position != old_position:
    old_position = driver.execute_script(position_script)
    time.sleep(1)
    driver.execute_script(
        """var scrollingElement = (document.scrollingElement ||
         document.body);scrollingElement.scrollTop =
         scrollingElement.scrollHeight;""")
    new_position = driver.execute_script(position_script)
source_page = driver.page_source
driver.quit()

# extract the url's and name's
counter = 1
element_to_find = 'amp;index={}" ar'
video_index = source_page.find(element_to_find.format(counter))  #'amp;index=1" ar'
while video_index != -1:
    title_element = ''
    count_name = video_index
    while title_element != 'title="':
        title_element = source_page[count_name: count_name + 7]
        count_name += 1
    count_name += 6
    start_title_position = count_name
    end_title = ''
    while end_title != '>':
        end_title = source_page[count_name]  # exit loop if end_title == '>'
        count_name += 1
    name = source_page[start_title_position:count_name - 2]  # extract the name of the video
    name = name.replace('"','"')
    video_id = source_page[video_index - 56: video_index - 45]  # extract video id
    print(str(counter)
          + '. link: ' + 'https://www.youtube.com/watch?v=' + video_id +
          ', name: ' + name)
    counter += 1
    video_index = source_page.find(element_to_find.format(counter))  # continue the next video

The easiest solution is:

from pytube import Playlist

URL_PLAYLIST = "https://www.youtube.com/playlist?list=YOUR-LINK"

# Retrieve URLs of videos from playlist
playlist = Playlist(URL_PLAYLIST)
print('Number Of Videos In playlist: %s' % len(playlist.video_urls))

urls = []
for url in playlist:
    urls.append(url)

print(urls)
