How to fix the incorrect regex between `### BEGIN CODE` and `### END CODE` to generate a list of names in the simple_string?

import re def names(): simple_string = """Amy is 5 years old, and her sister Mary is 2 years old. Ruth and Peter, their parents, have 3 kids."""

### BEGIN CODE pattern = r'[A-Za-z]?' match = re.finditer(pattern, simple_string) ### END CODE # YOUR CODE HERE raise NotImplementedError() return match names()

assert len(names()) == 4, "There are four names in the simple_string"
