[Tutor] error message

[Ron Nixon]

I'm dping something very simple in RE.

Lets say I'm trying to match an American Phone number

I write the code this way and try to match it:
import re
string = 'My phone is 410-995-1155'
pattern = r'\d{3}-\d{3}-\d{4}'
re.match(pattern,string).group()

but I get this error message
Traceback (most recent call last):
  File "C:/Python24/findphone", line 4, in -toplevel-
    re.match(pattern,string).group()
AttributeError: 'NoneType' object has no attribute 'group'
