When dealing with the drop-down box that appears after suspension , I have encountered the following two kinds of errors

One no such element:Unable to locate element: {“method”:“xpath”,“selector”:"//div[@class=‘s-user-setting-pfmenu’]/a[text()=‘ Advanced search ’]"}

In baidu home page , Hover the mouse over " Set up ", Then move to " Advanced search " And click the

Error code :

# wait for " Set up " Button appears 
WebDriverWait(dr,30).until(EC.visibility_of_element_located((By.XPATH,"//span[text()=' Set up ']")))
# use ActionChains The form of the chain , Move the mouse to " Set up ", And then click " Advanced search "
ac = ActionChains(dr)
ac.move_to_element(dr.find_element_by_xpath("//span[text()=' Set up ']")).\
click(dr.find_element_by_xpath("//div[@class='s-user-setting-pfmenu']/a[text()=' Advanced search ']")).perform()
# click() Medium dr Report errors 
time.sleep(5)
dr.quit()

Execution results

I'll follow ActionChains Step by step modification of , After modification, it still doesn't work
Finally, in turn perform move_to_element/click, Successful implementation
The modified code

dr = webdriver.Edge()
dr.get("http://www.baidu.com")
dr.maximize_window()
WebDriverWait(dr,30).until(EC.visibility_of_element_located((By.XPATH,"//span[text()=' Set up ']")))
ac = ActionChains(dr)
ac.move_to_element(dr.find_element_by_xpath("//span[text()=' Set up ']")).perform()
ac.click(dr.find_element_by_xpath("//div[@class='s-user-setting-pfmenu']/a[text()=' Advanced search ']")).perform()
time.sleep(5)
dr.quit()
