I don't know where is wrong here :c

Challenge Task 1 of 1

Create a variable named good_numbers that is an re.findall() where the pattern matches anything in string except the numbers 5, 6, and 7.

negate.py 
import re

string = '1234567890'

good_numbers = re.findall(r'[\d+][^567]', string)

You have two ranges in your re, and the first one accepts any digit (including 5, 6, or 7)

:point_right: Try writing your re so it has only one range which imposes the necessary restrictions.

You only need to negate 5, 6, or 7

Thanks Steven!
