Record the click problem of the select box in automatic test

1. Paste the code first

#Open the Google Chrome
driver=webdriver.Chrome();
#driver.fullscreen_window();
#input the Google
driver.get('https://www.google.com/');
#driver.find_element_by_xpath("//*[@id='tsf']/div[2]/div[1]/div[1]/div/div[2]/input").send_keys('新冠状病毒');
time.sleep(1);
#Click the I'm feel Luckly
driver.find_element_by_css_selector("#tsf > div:nth-child(2) > div.A8SBwf > div.FPdoLc.tfB0Bf > center > input.RNmpXc").click();
time.sleep(1);
# click about us
driver.find_element_by_css_selector("#nav-list > li:nth-child(2) > a").click();
time.sleep(1);
#Cyclic click on select checkbox
for index in range(len(driver.find_elements_by_tag_name("option"))):
    driver.refresh();
    select = driver.find_element_by_id("lang-chooser");
    select_value = select.find_elements_by_tag_name("option");
    time.sleep(2);
    select_value[index].click();
    time.sleep(2);

First, by_ tag_ The name method gets the option information in the select box, which is returned in the form of list

driver.find_elements_by_tag_name("option")

Then use the for loop to traverse the list of select options through the index number, and remove the current option of click ()
because each click on the select option will refresh the whole web page, an error will be reported

element is not attached to the page document

So we need to use it driver.refresh() method to refresh the current page, and then get the elements of the select option box again to click
