AttributeError: 'NoneType' object has no attribute 'groupdict' here is my code i used:

And if someone could explain how to add the code itself that would be great, bc i used a snapshot this time

it looks like you're working on the Compiling and Loops lesson of the Regular Expressions in Python course.

The issue seems to be caused by several missing punctuation symbols in the REGEX expression:

# code from snapshot:
line = re.compile(r'''
    ^(?P<name>[-\w ]+,\s[-\w ]+)\t  # Last and first names
    (P<email>[-\w\d.+]+@[-\w\d.]+)\t  # Email
    (P<phone>\(?\d{3}\)?-?\s?\d{3}-\d{4})?\t  # Phone
    (P<job>[\w\s]+,\s[\w\s]+)\t  # Job and company
    (P<twitter>@[\w\d]+)?$  # Twitter
''', re.X|re.M)

# instructor's code from lesson:
line = re.compile(r'''
    ^(?P<name>[-\w ]+,\s[-\w ]+)\t  # Last and first names
    (?P<email>[-\w\d.+]+@[-\w\d.]+)\t  # Email
    (?P<phone>\(?\d{3}\)?-?\s?\d{3}-\d{4})?\t  # Phone
    (?P<job>[\w\s]+,\s[\w\s.]+)\t?  # Job and company
    (?P<twitter>@[\w\d]+)?$  # Twitter
''', re.X|re.M)

This caused the search to fail and return a None, which of course has no groupdict method.

:bulb: For future questions, you can have the system provide a link to your course and lesson. Take a look at this video about Posting a Question.

:bulb: And the snapshot was a great choice as it is very helpful for analysis. But should you need to show code for other reasons (as I did here), check out this video on using Markdown formatting to preserve the code's appearance.
