I run to get some value as score.

score = soup.find('div', attrs={'class' : 'summarycount'})

I run 'print score' to get as follows.

<div class=\"summarycount\">524</div>

I need to extract the numbe开发者_如何学运维r part. I used re module but failed.

m = re.search("[^\d]+(\d+)", score)

TypeError: expected string or buffer

function search in re.py at line 142
return _compile(pattern, flags).search(string)

What's the return type of the find function?
How to get the number from the score variable?
Is there any easy way to let BeautifulSoup to return the value(in this case 524) itself?

It returns an object, which you can use for further searches or to extract its contents with score.contents:

from BeautifulSoup import BeautifulSoup

str = r'''
    <body>
    <div class="summarycount">524</div>
    <div class="foo">111</div>
    </body>
'''

soup = BeautifulSoup(str)
score = soup.find('div', attrs={'class' : 'summarycount'})

print type(score)
print score.contents

Prints:
