如何在不手动复制和粘贴的情况下循环遍历 python 生成的列表？

问题描述

背景

我对编码非常陌生，并且一直在通过视频和反复试验来学习。虽然它似乎已经失去了动力。

我能够使用 Helium（一种更简单的 Selenium 版本）下载一组 youtube 链接。但是，我想遍历这些列表以从中下载成绩单。

# Get the links
def Get_links():
    # For the class (categories with segments of @R_746_4045@ion),find them all
    Lnk = find_all(S('.style-scope ytd-video-renderer'))
    fin = []

    # Within this class,for l in Lnk:
        # These variables exist
        # The xpath that contains the links
        ind_links = find_all(S('//*[@id="thumbnail"]'))
        # links in this this xpath
        href_list = [e.web_element.get_attribute('href') for e in ind_links]
        # We want to separate the duplicates
        # for every link in the href_lists variable
        for i in href_list:
            # within the empty list 'fin',if it is not in the empty list,then we append it.
            # This makes sense because if there is nothing in the list,then there will only be one copy of the list of links
            if i not in fin:
                fin.append(i)
                
    print(fin)

输出是链接列表

问题

有没有一种方法可以让我进入这些链接，使用 Helium（或 Selenium）在浏览器中打开它们，然后下载成绩单，而无需手动复制和粘贴它们作为变量，然后将它们放在列表中？

解决方法

示例

带有网址的列表：

fin = ['https://www.youtube.com/watch?v=eHnXgh0j500',None,'https://www.youtube.com/watch?v=wDHtXXApfbc','https://www.youtube.com/watch?v=CJhOGDU636k'
  ]

循环列表并做一些事情：

for url in fin:
    if url: #check for the NONE values
        #do something in selenium e.g. driver.get(url)
        print(url) #or just print

dictionary list selenium url
