Where is my error in this regular expression?

I have to match all the numbers in the string, except "567". I except the three numbers with this "^", but I have an error and I don't know what I have to do. Thanks.

negate.py 
import re

string = '1234567890'
good_numbers = re.findall(r'\w+[^567]', string)

The error still appears, Now the output is: "12347890" That excluded only the numbers "56", but the "7" appears. Why?

This passes for me.

import re

string = '1234567890'


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