Python/Selenium列印元素值回傳<session="xxx",element="xxx">而不是想要的值

我正在嘗試撰寫一個回傳城市天氣的代碼。為此，我使用 selenium（我知道有更好的庫，但這是我最滿意的一個）。首先，我進行代碼搜索“天氣 xxx”，然后使用自動顯示所有資訊的谷歌功能。

然后我例如選擇溫度，有 th HTML，3 是我要列印的值：

<span class="wob_t q8U8x" id="wob_tm" style="display:inline">3</span>

但是當我列印它回傳時：

<selenium.webdriver.remote.webelement.WebElement (session="fb232f60015b08ee6db42b7fa83bd990", element="50c95ed2-17ce-41eb-835a-e7f9d0360540")>

如何轉換或導航輸出或 xpath 以獲取值？(3)

完整代碼：

from selenium.webdriver.common.keys import Keys as k
from selenium import webdriver
from selenium.webdriver.common.by import By

PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("https://google.com/")

def process():
    global temperature
    driver.find_element(By.XPATH,'//*[@id="L2AGLb"]/div').click()
    driver.find_element(By.NAME,'q').send_keys(city, ' weather' k.RETURN)
    temperature = driver.find_element(By.ID,'wob_tm')

city = input('City: ')
process()

print(temperature)
driver.quit()

PS，我使用 ID 來定位元素，但它回傳與 XPATH 等相同的“奇怪”輸出......

謝謝你的幫助

你的代碼幾乎是好的。您所缺少的只是從 web 元素中提取文本值。
這應該會更好：

from selenium.webdriver.common.keys import Keys as k
from selenium import webdriver
from selenium.webdriver.common.by import By

PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("https://google.com/")

def process():
    global temperature
    driver.find_element(By.XPATH,'//*[@id="L2AGLb"]/div').click()
    driver.find_element(By.NAME,'q').send_keys(city, ' weather' k.RETURN)
    temperature = driver.find_element(By.ID,'wob_tm')

city = input('City: ')
process()

print(temperature.text)
driver.quit()

您需要在此處添加等待，最好是預期條件顯式等待，如下所示：

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

PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("https://google.com/")
wait = WebDriverWait(driver, 20)


def process():
    global temperature
    wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="L2AGLb"]/div'))).click()

    wait.until(EC.visibility_of_element_located((By.NAME, 'q'))).send_keys(city, ' weather' k.RETURN)
    temperature = wait.until(EC.visibility_of_element_located((By.ID, 'wob_tm'))).text

city = input('City: ')
process()

print(temperature)
driver.quit()

感謝所有答案，這是我在@Prophet 的幫助下完成的代碼：

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

PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("https://google.com/")
wait = WebDriverWait(driver, 20)

def process():
    global temperature
    global precipitation
    global wind
    global humidity
    global time
    global forecast

    #accepting google cookies and selecting language
    wait.until(EC.visibility_of_element_located((By.CLASS_NAME,'V5OCtd'))).click()
    if language == 'en':
        wait.until(EC.visibility_of_element_located((By.XPATH,'//*[@id="tbTubd"]/div/li[13]'))).click()
    if language == 'fr':
        wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="tbTubd"]/div/li[18]'))).click()
    if language == 'de':
        wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="tbTubd"]/div/li[9]'))).click()

    wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="L2AGLb"]/div'))).click()

    #searching for weather
    wait.until(EC.visibility_of_element_located((By.NAME, 'q'))).send_keys(city, ' weather' k.RETURN)

    #scraping weather data and assigning to variables
    temperature = wait.until(EC.visibility_of_element_located((By.ID, 'wob_tm'))).text
    wind = wait.until(EC.visibility_of_element_located((By.ID, 'wob_ws'))).text
    precipitation = wait.until(EC.visibility_of_element_located((By.ID, 'wob_pp'))).text
    humidity = wait.until(EC.visibility_of_element_located((By.ID, 'wob_hm'))).text
    time = wait.until(EC.visibility_of_element_located((By.ID, 'wob_dts'))).text
    forecast = wait.until(EC.visibility_of_element_located((By.ID, 'wob_dc'))).text


def info():

    #printing weather info
    print('Date: ', time)
    print('Forecast: ', forecast)
    print('Temperature: ',temperature,'°C')
    print('Wind: ',wind)
    print('Precipitation: ', precipitation)
    print('Humidity: ', humidity)

#city and language input
city = input('City: ')
language = input('Language [en,fr,de]: ')
if language != 'fr':
    if language != 'de':
         if language !='en':
            print('Language not supported')
            exit()
process()
info()

#leave driver
driver.quit()
