使用BeautifulSoup将html表解析为python字典

这是一段html代码，我正试图用BeautifulSoup解析它：

<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>

正如我在代码中已经提到的，标签的数量不是固定的。此外，还可能有：

菜单1和菜单2

只是菜单1

只有菜单2

没有菜单1和菜单2（只有

）

例如，它可能看起来就像这样：

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

<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>

这始终是页面的第一个表，因此我可以使用：

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

提前感谢您的帮助
