python-经世优学网课挂学时脚本

老师要求每挂满150分钟的课程，然后就想着写一个脚本来挂学时，使用了selenium来模拟浏览器行为来写的一个挂网课脚本。

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
import time

uname = ''
paswd = ''

def open_brower():
    b = webdriver.Chrome()
    #打开经世优学网站
    b.get('http://study.huatec.com/')

    #设置等待时间直到找到元素
    user = WebDriverWait(b,10).until(lambda b:b.find_element_by_id('username'))
    user.clear()
    user.send_keys(uname)
    
    pwd = WebDriverWait(b,10).until(lambda b:b.find_element_by_id('password'))
    pwd.clear()
    pwd.send_keys(paswd)
    
    #点击登录
    b.find_element_by_class_name('btn-success').click()
    
    time.sleep(10)
    #用time模块来睡眠10S，让网站渲染出来
    std_data = b.find_element_by_link_text('学习数据')
    std_data.click()
	#打开第一门课程
    c1 = WebDriverWait(b,10).until(lambda b:b.find_element_by_xpath('//tbody/tr[1]/td[7]/div/a'))
    c1.click()
     #这个网站加载有点慢所以都加了睡眠时间等待网站渲染
    time.sleep(8)
   #把句柄切换到课程的句柄
    try:
        b.switch_to_window(b.window_handles[1])
