import re
string = '1234567890'
def good_numbers(string):
return(re.findall(r'\d', string))

The pattern currently matches any single digit. The task is to match any character (number or letter) except the numbers 5,6 and 7.
To create a character class to represent a single 5, 6, or 7, enclose these characters within square brackets: [567]
To match anything else outside of a specific character set, add a negation ^ as the first character: [^567]
Two additional corrections:
- the task is to create (as in assign to) a variable
good_numbers. You have created a function of that name instead. -
returnis not a function. It should be followed by a space and the return value need not be wrapped in parentheses.
Post back if you need more help. Good luck!!!
