运行代码后的效果图：


代码如下：

from selenium import webdriver
import time
driver=webdriver.Chrome()
driver.get('https://music.163.com/#/playlist?id=2829844572')
time.sleep(2)

iframe=driver.find_element_by_id('g_iframe')
driver.switch_to.frame(iframe)

parent=driver.find_element_by_id('m-playlist')

tbody=parent.find_element_by_tag_name('tbody')

trs=tbody.find_elements_by_tag_name('tr')

data=[]

for index,each in enumerate(trs):
    #序号
    num=each.find_element_by_class_name('num').text
    href=each.find_elements_by_tag_name('td')[1].find_element_by_tag_name('a').get_attribute('href')
    name=each.find_elements_by_tag_name('td')[1].find_element_by_tag_name('b').get_attribute('title')
    singer = each.find_elements_by_tag_name('td')[3].find_element_by_tag_name('div').get_attribute('title')

    data.append([num,href,name,singer])
