Question

次のコード行は、特定のプレイリストへのソースコードを提供し、すべてのURLを変数 "newlink"に格納します。私は、このURLの文字列を通り、 '/ watch？v ='という文字列をPythonの配列に格納して、配列[0]が私に最初のリンクarray [1]を与えるループを書いてみたい2番目のように。これを行う最善の方法は何でしょうか？

import re 
from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 
from bs4 import BeautifulSoup 
import requests 


#Asks which playlist you want downloaded 
print ('Which playlist do you want to download?') 
playlist = input() 

#Access my youtube playlists page 
driver = webdriver.Chrome(executable_path='E:\chromedriver\chromedriver.exe') 
driver.get("https://www.youtube.com/user/randomuser/playlists?sort=dd&view=1&shelf_id=0") 

#Access the 'classic' playlist 
if playlist == 'classic': 
    driver.find_element_by_xpath('//a[contains(text(), "classic")]').click() 
    newurl = driver.current_url 

    requrl = requests.get(newurl) 
    requrlcont = requrl.content 

    soup = BeautifulSoup(requrlcont, "html.parser") 
    for link in soup.find_all('a'): 
     newlink = link.get('href'))

このコードは、実際にアレイを作成したプレイリストでテストされています。

import re 
from selenium import webdriver 
from bs4 import BeautifulSoup 
import requests 

#Asks which playlist you want downloaded 
print ('Which playlist do you want to download?') 
playlist = raw_input() 

#Access my youtube playlists page 
driver = webdriver.Chrome(executable_path='/usr/lib/chromium-browser/chromedriver') 
driver.get("https://www.youtube.com/user/randomuser/playlists?sort=dd&view=1&shelf_id=0") 

#Access the 'Favorites' playlist 
if playlist == 'Favorites': 
    driver.find_element_by_xpath('//a[contains(text(), "Favorites")]').click() 
    newurl = driver.current_url 

    requrl = requests.get(newurl) 
    requrlcont = requrl.content 
    links = [] 
    soup = BeautifulSoup(requrlcont, "html.parser") 
    for link in soup.find_all('a'): 
     #print("link " + str(link)) 
     if re.match("/watch\?v=", link.get('href')): 
      links.append(link.get('href')) 

    print links
