要自动进行 Facebook登录 而无需对 用户名 和 密码 进行硬编码，可以使用此input()功能从控制台获取 用户输入
，如下所示：

from selenium import webdriver

driver = webdriver.Firefox(executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("https://www.facebook.com/")
emailid = input("What is your emailid?(Press enter at the end to continue):")
driver.find_element_by_xpath("//input[@id='email']").send_keys(emailid)
password = input("What is your password?(Press enter at the end to continue):")
driver.find_element_by_xpath("//input[@id='pass']").send_keys("password")
driver.find_element_by_xpath("//input[starts-with(@id, 'u_0_')][@value='Log In']").click()

控制台输出：

What is your emailid?(Press enter at the end to continue):gomathisubramanian@gmail.com
What is your password?(Press enter at the end to continue):gomathisubramanian
