#-*-coding:utf8-*-
import time
from selenium import webdriver

#运行chrome，打开浏览器
driver =webdriver.Firefox()
#设置浏览器窗口
driver.set_window_size(1080,800)

#设置全局操作时间
driver.implicitly_wait(10)

#打开网址
driver.get('https://kyfw.12306.cn/otn')
#睡五秒自动选择验证码
time.sleep(5)

time.sleep(5)
#出发地选择
driver.find_element_by_id("fromStationText").click()
# setTimeout(function(){debugger;}, 5000)

3.自动爬取yemi页面中的邮箱

import re
from selenium import webdriver

driver=webdriver.Firefox()
driver.get("http://home.baidu.com/home/index/contact_us")
doc=driver.page_source  #查看页面的源代码
emails=re.findall(r'[\w]+@[\w\.-]+',doc) #正则表达式匹配邮箱（字符串前加r表示原生字符串，\w表示匹配字母数字及下划线，findall返回的是一个匹配字符串的列表 ）
#循环打印匹配的邮箱
for email in emails:
    print(email)
