如何在python中分隔表中的每个tr？

Question

我正在尝试从http://www.livescore.co.uk/worldcup/tables/.I解析表。我在管理输出时遇到了问题。我只想在输出中显示文本，还想在显示所有td之后在每个tr上加一个分隔符。我是初学者，我正在尝试学习。所以呢有人能告诉我在做什么吗错了，有吗建议？你知道吗

from BeautifulSoup import BeautifulSoup
import urllib2

pageSource=urllib2.urlopen('http://www.livescore.com/worldcup/tables/').read()

soup = BeautifulSoup(pageSource)
alltables = soup.findAll( "table", {"class":"league-wc table bh"} )
results=[]
for table in alltables:
    rows = table.findAll('tr')
    lines=[]
    for tr in rows[1:]:
        cols = tr.findAll('td')
        for td in cols:

            text=td.renderContents().strip('\n')

            lines.append(text)




    text_table='\n'.join(lines) 
    print text_table

输出：

<a href="/worldcup/team-brazil/">Brazil</a>

给你：

from BeautifulSoup import BeautifulSoup
import urllib2

pageSource=urllib2.urlopen('http://www.livescore.com/worldcup/tables/').read()

soup = BeautifulSoup(pageSource)
alltables = soup.findAll( "table", {"class":"league-wc table bh"} )

results=[]
for table in alltables:
    rows = table.findAll('tr')
    _table = []
    for tr in rows[1:]:
        _row = []
        cols = tr.findAll('td')
        for td in cols:
            if td.findAll('a'):
                text=td.a.renderContents().strip()
            else:
                text=td.renderContents().strip()
            _row.append(text)
        _table.append(_row)
    results.append(_table)


# print results
index = 1
for table in results:
    for row in table:
        print ','.join([str(index)] + row[1:])
        index += 1

输出：

1,Brazil,0,0,0,0,0,0,0,0
2,Cameroon,0,0,0,0,0,0,0,0
3,Croatia,0,0,0,0,0,0,0,0
4,Mexico,0,0,0,0,0,0,0,0
5,Australia,0,0,0,0,0,0,0,0
6,Chile,0,0,0,0,0,0,0,0
...

其思想是先收集原始数据，然后编写逻辑来显示数据（以任何方式）。你知道吗
