Treehouse Moderator 28,722 PointsThe challenge is looking for an application of regular expression re.findall() that will "recognize" numbers in a string but will exclude anything that contains 5, 6, or 7. You have to figure out what the regular expression might be.
Your challenge is to write a regular expression and fill in SomeRegularExpression (below)
import re
string = '1234567890'
good_numbers = re.findall(SomeRegularExpression, string)
