python - BeautifulSoup, a dictionary from an HTML table

I am trying to scrape table data from a website.

Here is a simple example table:

t = '<html><table>' +
    '<tr><td class="label"> a </td> <td> 1 </td></tr>' +
    '<tr><td class="label"> b </td> <td> 2 </td></tr>' +
    '<tr><td class="label"> c </td> <td> 3 </td></tr>' +
    '<tr><td class="label"> d </td> <td> 4 </td></tr>' +
    '</table></html>'

Desired parse result is {' a ': ' 1 ', ' b ': ' 2 ', ' c ': ' 3 ', ' d ' : ' 4' }


This is my closest attempt so far:

for tr in s.findAll('tr'):
  k, v = BeautifulSoup(str(tr)).findAll('td')
  d[str(k)] = str(v)

Result is:

{'<td class="label"> a </td>': '<td> 1 </td>', '<td class="label"> d </td>': '<td> 4 </td>', '<td class="label"> b </td>': '<td> 2 </td>', '<td class="label"> c </td>': '<td> 3 </td>'}

I'm aware of the text=True parameter of findAll() but I'm not getting the expected results when I use it.

I'm using python 2.6 and BeautifulSoup3.

Try this:

from BeautifulSoup import BeautifulSoup, Comment

t = '<html><table>' +
    '<tr><td class="label"> a </td> <td> 1 </td></tr>' +
    '<tr><td class="label"> b </td> <td> 2 </td></tr>' +
    '<tr><td class="label"> c </td> <td> 3 </td></tr>' +
    '<tr><td class="label"> d </td> <td> 4 </td></tr>' +
    '</table></html>'

bs = BeautifulSoup(t)

results = {}
for row in bs.findAll('tr'):
    aux = row.findAll('td')
    results[aux[0].string] = aux[1].string

print results
