I'm not understand on Regular Expressions > Escape Hatches > Challenge 2/2

May you please advise what i need to do on this challenge... I stuck here for 3 days.. I got only Bummer! Try again! so, I don't know what I missing.

Now, write a function named numbers() that takes two arguments: a count as an integer and a string. Return an re.search for exactly count numbers in the string. Remember, you can multiply strings and integers to create your pattern.

For example: r"\w" * 5 would create r"\w\w\w\w\w".

escapes.py 
import re

def first_number(arg1):
    return re.search(r'\d', arg1)


def numbers(count, text):
    return re.search(r'\b{}\b'.format(r'\S' * count), text)

numbers should look almost the same as first_number. The only difference is that you need to multiply '\d' by count:

def first_number(count, text):
    return re.search(r'\d' * count, text)

I hope this helps!
