我正在尝试使用Python和Selenium在Craigslist中自动执行任务。一切都很顺利，直到我不得不“添加图片”。我编写代码点击“添加图片”按钮，它打开了一个对话框（我认为这就是所谓的）。我想选择2个图像，然后单击“打开”按钮，但我不知道如何为它编写代码。我在网上看了几个例子，但没有真正对我说话。
下面是对话框的屏幕截图，蓝色突出显示我想要选择的图片：
此外，这是我的代码：
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://dallas.craigslist.org/")
# Click on "computer" link
driver.find_element_by_link_text("computer").click()
#Post
driver.find_element_by_link_text("post").click()
#Gig Offered radion button
driver.find_element_by_xpath("/html/body/article/section/form/ul/li[2]/label/span[2]").click()
# I want to hire someone
driver.find_element_by_xpath("/html/body/article/section/form/label[1]").click()
#Please choose a category: Computer Gigs"
driver.find_element_by_xpath("//*[@id='picker']/ul/li[1]/label/span[2]").click()
# Choose the location
driver.find_element_by_xpath("/html/body/article/section/form/ul/li[1]/label/input").click()
# Enter text
# Enter Posting Title
posting = driver.find_element_by_id("PostingTitle")
posting.send_keys("[SEEKING] Parents with Kids who Play Sports. Save Money on College!")
# Enter Location
area = driver.find_element_by_id("GeographicArea")
area.send_keys("Dallas Area")
# Enter Zip Code
zipcode = driver.find_element_by_id("postal_code")
zipcode.send_keys("75001")
# Enter Body
body = driver.find_element_by_id("PostingBody")
body.send_keys("this is a test)
# No Pay
driver.find_element_by_xpath("//*[@id='vol_label']/input").click()

fromemail = driver.find_element_by_id("FromEMail")
fromemail.send_keys("foo@gmail.com")
# Confirm Email

confirmemail.send_keys("foo@gmail.com")
