python - finding email address in a web page using regular expression -


i'm beginner-level student of python. here code have find instances of email addresses web page.

    page = urllib.request.urlopen("http://website/category")     reg_ex = re.compile(r'[-a-z0-9._]+@([-a-z0-9]+)(\.[-a-z0-9]+)+', re.ignorecase     m = reg_ex.search_all(page)     m.group()

when ran it, python module said there invalid syntax , on line:

    m = reg_ex.search_all(page)

would tell me why invalid?

consider alternative: 

## suppose have text many email addresses str = 'purple alice@google.com, blah monkey bob@abc.com blah dishwasher'  ## here re.findall() returns list of found email strings emails = re.findall(r'[\w\.-]+@[\w\.-]+', str)      ## ['alice@google.com', 'bob@abc.com']     email in emails:     # each found email string     print email
