1. Loop through all drop-down list values

   <!--Practicing html-->
     //Education background: < select id = "ZZ" name = "SS" size = "1" >
                   <option value ="you">Kindergarten</option>
                   <option value ="xiao">Primary school</option>
                   <option value ="chu">Junior middle school</option>
                   <option value ="gao">high school</option>
                   <option value ="da">University</option>
              </select>

from selenium import webdriver
#Import select module
from selenium.webdriver.support.select import Select
driver  = webdriver.Firefox(executable_path="d:\\geckodriver")
url = "file:///d:/day8.html"
driver.get(url)
#Locate drop-down menu
select_element = driver.find_element_by_id("zz")
#Save all the content and assign it to options. Note that here are all the elements, so use elements
options = select_element.find_elements_by_tag_name("option")
#Cycle display plus printing
for option in options:
    print("Option display text:",option.text)
    print("The option values are:",option.get_attribute("value"))
    option.click()
    import time
    time.sleep(1)

2. Radio drop-down list

from selenium import webdriver
from selenium.webdriver.support.select import Select
driver  = webdriver.Firefox(executable_path="E:\\geckodriver.exe")
driver.get("file:///d:/day8.html")
#Locate drop-down menu
xiala = driver.find_element_by_id("zz")
#Select by serial number. The serial number starts from 0 and 2 is junior high school
Select(xiala).select_by_index(2)
#Select high school through value attribute value selection
Select(xiala).select_by_value("gao")
#Select university directly through text value selection
Select(xiala).select_by_visible_text(u"University")

3. Selection and cancellation of multi selection list

   <!--Practicing html-->
             //Education background: < select id = "ZZ" name = "SS" size = "6" multiple = "true" >
                   <option value ="you">Kindergarten</option>
                   <option value ="xiao">Primary school</option>
                   <option value ="chu">Junior middle school</option>
                   <option value ="gao">high school</option>
                   <option value ="da">University</option>
              </select>

from selenium import webdriver
from selenium.webdriver.support.select import Select
driver  = webdriver.Firefox(executable_path="E:\\geckodriver.exe")
driver.get("file:///d:/day8.html")
#Locate drop-down menu
xiala = driver.find_element_by_id("zz")
#Choose junior high school, senior high school and university after multiple choices
Select(xiala).select_by_index(2)
Select(xiala).select_by_value("gao")
Select(xiala).select_by_visible_text(u"University")
#Cancel the selected content (abbreviated below, just add more de than the selection, and the last one is to cancel all the selected content)
Select(xiala).deselect_by_index(2)
Select(xiala).deselect_by_value("gao")
Select(xiala).deselect_by_visible_text(u"University")
Select(xiala).deselect_all()

4. Operate the radio box, multi box, assert and select all

   <! -- HTML for practice -- >

      <! -- single choice -- > < p >
             Gender: male < input type = "radio" name = "R1" checked / >
                   Female < input type = "radio" name = "R1" / >
                   Unknown < input type = "radio" name = "R1" / >
           </p>
    <! -- mu lt iple choice
             Hobbies: Games < input type = "checkbox" name = "C1" checked / >
                   Literature and art < input type = "checkbox" name = "C2" / >
                   Sleep < input type = "checkbox" name = "C3" / >
           </p>

from selenium import webdriver
driver  = webdriver.Firefox(executable_path="E:\\geckodriver.exe")
driver.get("file:///d:/day8.html")
#For the simplest single choice and multiple choice, click the selection box directly, and then click the single choice female below.
xuanzhong = driver.find_element_by_xpath("/html/body/form/p[2]/input[2]")
xuanzhong.click()
#Whether the assertion is selected (the choice needs to be used with the framework)
assertTrue(xuanzhong.is_selected(),u"Women are not selected")
#Select all the multi selection options at one time (be sure to note that they are elements because of multi selection at one time)
#Note: because the game is the default, the next click is to cancel the selection. The following result is to select literature and art and sleep
duoxuan = driver.find_elements_by_xpath(".//*[@type='checkbox']")
for i in duoxuan:
    i.click()

5. Assert keywords in page source code

from selenium import webdriver
driver  = webdriver.Firefox(executable_path="E:\\geckodriver.exe")
driver.get("https://www.baidu.com")
driver.find_element_by_id("kw").send_keys("WIKTK")
driver.find_element_by_id("su").click()
import time
time.sleep(4)
#Assert keywords in page source code
assert "WIKTK" in driver.page_source, u"The keyword does not exist in the source code of the page"

6. screenshots

from selenium import webdriver
driver  = webdriver.Firefox(executable_path="E:\\geckodriver.exe")
driver.get("https://www.baidu.com")
driver.save_screenshot(r"d:\screenshot.png")

7. Drag page elements

http://jqueryui.com/resources/demos/draggable/scroll.html

from selenium import webdriver
driver = webdriver.Firefox(executable_path="E:\\geckodriver.exe")
driver.get("http://jqueryui.com/resources/demos/draggable/scroll.html")
#Positioning the first, second and third drag boxes
yi = driver.find_element_by_id("draggable")
er = driver.find_element_by_id("draggable2")
san = driver.find_element_by_id("draggable3")

#Import drag element method module
from selenium.webdriver import ActionChains

a_chains = ActionChains(driver)
#First box drag to second box
a_chains.drag_and_drop(yi, er).perform()
#Pan the third box 500
a_chains.drag_and_drop_by_offset(san,500, 0).perform()
