Question

下面是我的代码，

[Paused after "<step text>" - press enter to continue]

上面代码的输出是下面的

from selenium import webdriver
import time
from selenium.webdriver.support.ui import WebDriverWait as wait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException
xpath='//ol[@class="ranking"]'
driver=webdriver.Ie("C:\Users\test\Downloads\IEDriverServer_Win32_3.0.0\IEDriverServer.exe")
driver.get('https://www.havocscope.com/country-profile/')
state=[states.find_elements_by_css_selector('li a') for states in driver.find_elements_by_xpath(xpath)]
print (state)

现在，我对如何通过单击每个链接，转到下一页并返回导航来进行迭代感到困惑。我在下面尝试了for循环，但是没有用。另外，如果我在代码中包括print len（state），它会显示1.可能是因为“ state”是列表中的列表（请注意print（状态）的o / p中有2个方括号）。如果是这样，我如何将其转换为一个列表？

下面是html

for i in range (0,len(state)):
    state[i].click()

Answer 1

state已经是列表，因为您使用的是states.find_elements_by_css_selector而不是states.find_element_by_css_selector

因此将其更改为更像这样的内容：

ranking = driver.find_element_by_xpath(xpath) # notice I use element
num_countries=len(ranking.find_elements_by_css_selector('li'))
for i in range(num_countries):
    # you need to refetch countries every time so the elements aren't stale
    ranking = driver.find_element_by_xpath(xpath)
    countries = ranking.find_elements_by_css_selector('li a')
    country = countries[i]
    # do what you need with the state now
    country()
    assert country == driver.find_element_by_css_selector('#content_box li h2').text  # make sure the country is the correct one
    # go back
    driver.back()

注意：因为它们是国家，所以我将var重命名为countries。
