from selenium import webdriver
from selenium.webdriver.common.keys import Keys
chrome_path=r"C:\Users\Priyanshu\Downloads\Compressed\chromedriver_win32\chromedriver.exe"
driver=webdriver.Chrome(chrome_path)
driver.get("https://www.flipkart.com/search?q=laptop&otracker=start&as-show=off&as=off")

driver.find_element_by_xpath(""" //*[@id="container"]/div/div[2]/div[2]/div/div[2]/div[2]/div/section/ul/li[2]""").click()

我在最后一行代码中没有出现这样的元素。

{{1}}

如果我这样做,它的工作正常。

该元素无法立即使用,wait for it to be present first

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


wait = WebDriverWait(driver, 10)

search = wait.until(EC.presence_of_element_located((By.NAME, 'q')))
search.send_keys("laptop")
search.send_keys(Keys.RETURN)

element = wait.until(EC.presence_of_element_located(By.XPATH, '//*[@id="container"]/div/div[2]/div[2]/div/div[2]/div[2]/div/section/ul/li[2]'))
element.click()

请注意,假设您想要进入" Popularity"菜单标题,为什么不简化XPath表达式并使用元素的文本:

//li[. = "Popularity"]
