欢迎来到StackOverflow！ 请阅读我们常见问题解答的How to ask a question部分。你知道吗

Explain how you encountered the problem you're trying to solve, and any difficulties that have prevented you from solving it yourself.

到目前为止，你试图用什么方法来解决这个问题？你知道吗

让我们给你一个开始。你知道吗

你只需要^{}和^{}函数。你知道吗

soup = BeautifulSoup(html_string)

status = soup.find('img').get('alt')  # get 'alt' content of the first <img> tag.

# find the first <td> tag with a class="test", get its content, split it using spaces,
version = soup.find('td', class_='test').text.split()[0]  # and get the first substring
time_start = soup.find('div', class_='start').text
time_end = soup.find('div', class_='end').text
user = soup.find_all('td')[2].text  # get a third <td>'s content.

print status  # QUEUED
print version  # v1402beta_150127_1_OTM_TICKETS_dv_c_UID142307274200
print time_start  # (04.02) 23:29
print time_end  # ~  >        () >
print user  # mcordeix

你只需阅读bs4's documentation10分钟，然后自己试一试。
只需弹出Python解释器，分配html_string变量，导入beautifulsoup库，然后重试。你知道吗

我相信你可以自己解决time_end内容留下的问题。没那么难。你知道吗
