Python crawler Selenium warning box of pop up processing

JavaScript has three pop-up windows: Alert (only OK button), Confirmation (OK, Cancel button, etc.) and Prompt (with input dialog box), and the pop-up window cannot be positioned by front-end tools. At this time, this pop-up window can be positioned by switch_to. alert method, and a series of operations can be performed.
The key methods used in this chapter are as follows:
switch_to. alert: Navigate to warning box text: Get text information in warning box accept (): Accept existing warning box (equivalent to acknowledgement) dismiss (): Dissolve existing warning box (equivalent to cancel) send_keys ('Text Content'): Send text to the warning box (for pop-up windows with input dialog boxes) click (): Mouse click event (see Python crawler-Selenium (5) mouse event for other mouse events) move_to_element (): Mouse hover (see Python crawler-Selenium (5) mouse event for details)
from selenium import webdriver
from selenium.webdriver import ActionChains
import time
driver = webdriver.Chrome()
driver.get('http://www.baidu.com')
# Hover the mouse over the Settings link
link = driver.find_element_by_link_text(' Settings ')
ActionChains(driver).move_to_element(link).perform()
time.sleep(2) # Sleep for two seconds and watch 1 Lower effect
# Open search settings
driver.find_element_by_link_text(" Search settings ").click()
time.sleep(2) # Sleep for two seconds and watch 1 Lower effect
# Save Settings
driver.find_element_by_class_name("prefpanelgo").click()
time.sleep(2) # Sleep for two seconds and watch 1 Lower effect
# Locate warning box
alert = driver.switch_to.alert
print(alert.text) # Print warning box contents
#alert.send_keys(' Input content ') # This test site is not a pop-up window of input type, so comment it out first
alert.accept() # Accept the existing warning box, which is equivalent to confirming
#alert.dismiss() # Dissolving an existing warning box is equivalent to canceling
time.sleep(2) # Sleep for two seconds and watch 1 Lower effect
driver.quit()
