如何使用SeleniumPython指定要打印的数据

Question

我有这个代码：

from keyboard import press_and_release
from selenium import webdriver
from selenium.webdriver.common.by import By
url = 'https://www.yr.no/nb'
def weather(url, webdriver):
webdriver.get(url)  # Goes to the HTML-page of the given URL
for li_values in webdriver.find_elements(By.CSS_SELECTOR, "ol.daily-weather-list__intervals li"):
print(li_values.text + "n")

def forecast():
print('Hello, I can search up the weather for you.')
driver = webdriver.Chrome(r"C:UsersAmalieDownloadschromedriver_win32chromedriver.exe")  # Open Google Chrome
driver.get(url)  # Goes to the HTML-page of the given URL
while True:
inp = input('Where shall I search? Enter a place in :').capitalize()  # Ask for input
print('Alright, checking the weather in ' + inp + '...')
"Search for a place"
driver.find_element_by_id("page-header__search-button").click()  # Find and click on search input box
driver.find_element_by_id("page-header__search-input").send_keys(inp)  # Enter input
press_and_release('enter')  # Click enters
driver.find_element_by_xpath('//*[@id="page-header__search"]/ol/li[1]').click()  # Click on 1st suggested option
break
cURL = driver.current_url
weather(cURL, driver)
driver.close()
driver.quit()
forecast()

这给了我这个输出：

Hello, I can search up the weather for you.
Where shall I search? Enter a place in :bergen
Alright, checking the weather in Bergen...

等等。。。

我如何选择只打印今天、明天等的数据，如下所示：

I dag 14. juni
Ettermiddag: skyet
Kveld: skyet
Maksimum/minimum temperatur:
13°/12°
Nedbør
0,5mm
Tirsdag 15. juni

Maksimum/minimum temperatur:

我知道xpath，但我认为我必须使用标识符或类似的东西，但我对HTML非常陌生，所以我不知道是否已经有了这个函数，或者我是否必须自己编写代码。

Answer 1

例如，要从列表中获取前两项，可以执行以下操作：

def weather(webdriver):
webdriver.get(url)  # Goes to the HTML-page of the given URL
list_xpath = "//ol[@class='daily-weather-list__intervals']/li[@class='daily-weather-list-item']"
all_items = webdriver.find_elements_by_xpath(list_xpath)
for li_values in all_items[:2]:
print(li_values.text + "n")
