chrome_options = webdriver.ChromeOptions()
#启用无界面模式
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(chrome_options=chrome_options)
url = "file:///E:/log/index.html"
driver.get(url)
keys = []
for i in range(1,13):
    #使用format代替%s
    key = driver.find_element_by_xpath('//*[@id="statisticsTable"]/thead/tr/th[{id}]/div'.format(id = i)).text
    keys.append(key)

valuestr = driver.find_element_by_xpath('//*[@id="statisticsTable"]/tbody[2]/tr').text
values = valuestr.split(" ")
#字典推导式，in后面必须加元祖或zip的迭代器等

dict = {key: value for key,value in zip(keys, values)}
print(dict)

driver.close()
