python - Can re.findall() return only the part of the regex in parens? -

looping through data, want capture string of numbers appear page ids (with more 1 per line.) however, want match number strings part of particular url, don't want record url, number.

urls relative, digits strings of variable length, of form

/view/123456.htm 

data returned here '123456'

i using re.findall identify right urls, , re.sub extract number strings.

views = re.findall(r"/view/\d*?.htm", line) view in views:     view = re.sub(r"/view/(\d+).htm", r"\1", view)     pagelist.append(view) 

is there way

views = re.findall(r"/view/(\d*?).htm", r"\1", line)   #i know doesn't work 

where original findall() returns part of match in parens?

can re.findall() return part of regex in parens?

it not can, does:

>>> import re >>> re.findall(r"/view/(\d*?).htm", "/view/123.htm /view/456.htm") ['123', '456'] 

did not try it? the documentation describes well.
