from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

def message(emailaddr,text):
    browser = webdriver.Firefox()
    browser.get('https://email.163.com/')
    time.sleep(2)

    iframe = browser.find_element_by_tag_name('iframe')
    browser.switch_to_frame(iframe)
    login = browser.find_element_by_name('email')
    print(login.tag_name,login.text)
    login.send_keys('your_email',Keys.TAB,'password')
    land = browser.find_element_by_id('dologin').click()
    time.sleep(2)

    browser.switch_to.default_content()  # 退出frame，没有这一句后续的元素定位会出错
    writhe = browser.find_element_by_id('_mail_component_59_59')
    writhe.click()

    writher = browser.find_element_by_xpath('/html/body/div[2]/div[1]/div[2]/div[1]/section/header/div[1]/div[1]/div/div[2]/div/input')
    writher.send_keys(emailAddr,Keys.TAB,'Mail_theme',Keys.TAB,text)
    time.sleep(2)
    setd = browser.find_element_by_xpath('//*[@id="_mail_button_9_223"]').click()

emailAddr = input('Recipient's mailbox address :')
text = input('Mail content :')

message(emailAddr,text)

笔记：

直接用browser.find_element_by_ 是找不到#document内元素的

browser.switch_to_frame('id') #参数为id的值，若id值为变数可用下列代码转换

 iframe = browser.find_element_by_tag_name('iframe')
 browser.switch_to_frame(iframe)

switch_to_frame()用完需要退出，否则后继操作可能会异常

Message: TypeError: can't access dead object

_xpath()的参数最好直接在对象元素源代码上Copy->XPath

switch_to_frame() 的借鉴及其它知识：https://www.cnblogs.com/ketangxiaohai/p/9216483.html
