Answer 1

要从统计页面中提取玩家的信息，您可以使用以下解决方案：

代码块：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("http://www.ultimatetennisstatistics.com/playerProfile?playerId=4742")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//ul[@id='playerPills']//a[@class='dropdown-toggle'][normalize-space()='Statistics']"))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//ul[@class='dropdown-menu']//a[@id='statisticsPill'][normalize-space()='Statistics']"))).click()
statistics_items = WebDriverWait(driver, 10).until(EC.visibility_of_any_elements_located((By.XPATH, "//table[@class='table table-condensed table-hover table-striped']//tbody//tr/td")))
statistics_value = WebDriverWait(driver, 10).until(EC.visibility_of_any_elements_located((By.XPATH, "//table[@class='table table-condensed table-hover table-striped']//tbody//tr//following::th[1]")))
for item, value in zip(statistics_items, statistics_value):
    print('{} {}'.format(item.text, value.text))

控制台输出：

Ace % 4.0%
Double Fault % 2.1%
1st Serve % 68.7%
1st Serve Won % 71.8%
2nd Serve Won % 57.3%
Break Points Saved % 66.3%
Service Points Won % 67.2%
Service Games Won % 85.6%
Ace Against % Return
Double Fault Against % 7.2%
1st Srv. Return Won % 3.4%
2nd Srv. Return Won % 34.2%
Break Points Won % 55.3%
Return Points Won % 44.9%
Return Games Won % 42.4%
Points Dominance 33.3%
Games Dominance Total
Break Points Ratio 1.29
Total Points Won % 2.31
Games Won % 1.33
Sets Won % 54.4%
Matches Won % 59.7%
Match Time 77.2%

问题出在这条线的位置 -

soup = BeautifulSoup(driver.page_source,"lxml")

它应该在您单击 "Statistics" 选项卡后出现。因为只有 table loads 和 soup 可以解析它。

最终代码-

from selenium import webdriver
from bs4 import BeautifulSoup
import time

driver = webdriver.Chrome(executable_path=r'//path/chromedriver.exe')
driver.get("http://www.ultimatetennisstatistics.com/playerProfile?playerId=4742")

try:
   dropdown = driver.find_element_by_xpath('//*[@id="playerPills"]/li[9]/a')
   dropdown.click()
   bm = driver.find_element_by_id('statisticsPill')
   bm.click()
   driver.maximize_window()
   soup = BeautifulSoup(driver.page_source,"lxml")
   for i in soup.select('#statisticsOverview table tr'):
     print(i.text)
     data1 = [x.get_text(strip=True) for x in i.select("th,td")]
     print(data1)

except ValueError:
      print("error")
