You could also create a recurrence constraint by adding a value and perhaps a comma between curly braces ({}). And for that method you may want to build up the regex string using formatting or concatenation.

7,561 PointsYou don't need the extra ' ' around "\w"*count and the \w is still a \d like from the first challenge.
a passing example below:
import re
def first_number(string_argument): return re.search(r"\d", string_argument)
def numbers(count_int, count_str): return re.search(r"\d" * count_int, count_str)
