regex grouping question

consider my code:

contacts = re.search(r'(?P<email>[-\w.+]+@[-\w.]+),\s(?P<phone>[\d{3}-\d{3}-\d{4}]+)', string)

am I now right to presume that the fact that I didn't group ,\s makes the engine ommit comma's and white space from my search. I did F around with that comma in particular, it kept showing up on the mail adresses.

Thanks in advance and greetings

Your comma and space separators look good, and you didn't say what kind of problem you were having, but...

:point_right: It looks like you have mixed a group and a character class in the phone section.

I suspect the brackets and plus sign marked below don't really belong:

(?P<email>[-\w.+]+@[-\w.]+),\s(?P<phone>[\d{3}-\d{3}-\d{4}]+)

Hi Laurens,

Try this: 

(?P<email>[-\w.+]+@[-\w.]+),\s(?P<phone>[-\d+]+)

Bad character range if you include too many in a set.

Hope it works!
