Hi,

I would like my code to return '(415)'. What am i doing wrong?

phoneNumRegex=re.compile(r'(\(\d\d\d\))(\d\d\d-\d\d\d\d)')
mo=phoneNumRegex.search('My phonenumber is (415) 555-4242.')
mo.group(1)
Traceback (most recent call last):
  File "<pyshell#19>", line 1, in <module>
    mo.group(1)
AttributeError: 'NoneType' object has no attribute 'group'

Thank you, that site for Regex testing is very useful.

Can also match previous integer,then don't have to type \d for every one.
So if group number in eg two groups.

import re

phoneNumRegex = re.compile(r'(\(\d{3}\))\s(\d.*)\.')
mo = phoneNumRegex.search('My phonenumber is (415) 555-4242.')

>>> mo.group(1)
'(415)'
>>> mo.group(2)
'555-4242'
>>> mo.groups()
('(415)', '555-4242')
