PythonSelenium.send_keys()在元素更改類后不起作用

我正在嘗試使用 python 將我想離開的城市名稱輸入到 Google Flights 中。在 html 代碼中找到元素（輸入框）后，我注意到一旦您與元素互動，它的類就會從 更改為。因此driver.find_element(By.CSS_SELECTOR, '.LbIaRd').send_keys(city_name)只能在輸入框更改類之前發送字串的第一個字符。但是，在它更改其類后，我無法向該元素發送任何文本。

我嘗試與元素互動以更改其類，然后將相同的方法應用于輸入框的新類：

x = driver.find_elements(By.CSS_SELECTOR, '.LbIaRd')[0]
x.click()
time.sleep(2)
driver.find_element(By.CSS_SELECTOR, '.VfPpkd-ksKsZd-mWPk3d-OWXEXe-AHe6Kc-XpnDCe').send_keys(city_name)

代碼以沒有錯誤結束，但文本未發送到輸入框。只有一個元素帶有.VfPpkd-ksKsZd-mWPk3d-OWXEXe-AHe6Kc-XpnDCe定位器。

我還嘗試在更改類后單擊該元素，然后發送密鑰：

x = driver.find_elements(By.CSS_SELECTOR, '.LbIaRd')[0]
x.click()
time.sleep(2)
driver.find_element(By.CSS_SELECTOR, '.VfPpkd-ksKsZd-mWPk3d-OWXEXe-AHe6Kc-XpnDCe').click()
driver.find_element(By.CSS_SELECTOR, '.VfPpkd-ksKsZd-mWPk3d-OWXEXe-AHe6Kc-XpnDCe').send_keys(city_name)

但我得到以下例外：

selenium.common.exceptions.ElementClickInterceptedException:
Message: element click intercepted:
Element <input class="II2One j0Ppje zmMKJ LbIaRd VfPpkd-ksKsZd-mWPk3d-OWXEXe-AHe6Kc-XpnDCe, redacted html code">
is not clickable at point (612, 472).
Other element would receive the click: <input class="II2One j0Ppje zmMKJ LbIaRd", redacted html code>

任何幫助將不勝感激。

像這樣的東西？嘗試使用 ActionChains 發送密鑰，而不是使用 send_keys 函式
