Create a Python script that uses regular expressions to find all phone numbers in a string.
The following phone number should be found: (111) 111-1111
import re

phone_string = "(111) 111-1111"

phone_numbers = re.findall(r'\(?\d{3}\)?-?\s?\d{3}-\d{4}', phone_string)

for number in phone_numbers:
 print(number)
# Output: (111) 111-1111
