使用BeautifulSoup将html表解析为python字典

Question

This is an html code than I'm trying to parse with BeautifulSoup:

<table>
          <tr>
            <th width="100">menu1</th>
            <td>
              <ul class="classno1" style="margin-bottom:10;">
                    <li>Some data1</li>
                    <li>Foo1<a href="/link/to/bar1">Bar1</a></li>
                    ... (amount of this tags isn't fixed)
              </ul>
            </td>
          </tr>
          <tr>
            <th width="100">menu2</th>
            <td>
              <ul class="classno1" style="margin-bottom:10;">
                    <li>Some data2</li>
                    <li>Foo2<a href="/link/to/bar2">Bar2</a></li>
                    <li>Foo3<a href="/link/to/bar3">Bar3</a></li>
                    <li>Some data3</li>
                    ... (amount of this tags isn't fixed too)
              </ul>
            </td>
          </tr>
</table>

The output I would like to get is a dictionary like this:

DICT = {
    'menu1': ['Some data1','Foo1 Bar1'],
    'menu2': ['Some data2','Foo2 Bar2','Foo3 Bar3','Some data3'],
}

As I already mentioned in the code, amount of <li> tags is not fixed. Additionally, there could be:

menu1 and menu2

just menu1

just menu2

no menu1 and menu2 (just <table></table> )

so eg it could looks just like this:

 <table> <tr> <th width="100">menu1</th> <td> <ul class="classno1" style="margin-bottom:10;"> <li>Some data1</li> <li>Foo1<a href="/link/to/bar1">Bar1</a></li> ... (amount of this tags isn't fixed) </ul> </td> </tr> </table> 

I was trying to use this example but with no success. I think it's because of that <ul> tags, I can't read proper data from table. Problem for me is also variable amount of menus and <li> tags. So my question is how to parse this particular table to python dictionary? I should mention that I already parsed some simple data with .text attribute of BeautifulSoup handler so it would be nice if I could just keep it as is.

 request = c.get('http://example.com/somepage.html) soup = bs(request.text) 

and this is always the first table of the page, so I can get it with:

 table = soup.find_all('table')[0] 

Thank you in advance for any help.
