调理硒有问题

如何解决调理硒有问题

有问题（“ if”部分）。

它不等我单击左箭头（例如）来执行任务并立即运行它。

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("https://www.google.com/")
if Keys.ARROW_LEFT:
    element = driver.find_element_by_css_selector('.gLFyf')
    element.send_keys('khkh')
    element.send_keys(Keys.ENTER)

解决方法

声明if Keys.ARROW_LEFT:将始终为真

您必须使用服务员。
implicitly_wait或WebDriverWait

所以会

driver = webdriver.Firefox()
driver.implicitly_wait(10)
driver.get("https://www.google.com/")
element = driver.find_element_by_css_selector('.gLFyf')
element.send_keys('khkh')
element.send_keys(Keys.ENTER)

或

driver = webdriver.Firefox()
driver.get("https://www.google.com/")
element = WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.CSS_SELECTOR,".gLFyf")))
element = driver.find_element_by_css_selector('.gLFyf')
element.send_keys('khkh')
element.send_keys(Keys.ENTER)
