Can Someone explain this question plz:

Challenge Task 2 of 2

Now, write a function named numbers() that takes two arguments: a count as an integer and a string. Return a match 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".

I don't need the answer just to understand the question

thank you

escapes.py 
import re
def first_number(string):
      return re.search(r'\d',string)
def numbers(count, string)

Its asking you to show your understanding of cocatenation, Mourad. Essentially, just show with Python how you'd go about multiplying the regular expression number operator by the number variable and then search for it in the relevant string. So, get a count and a string. In that string, find where there are count numbers in a row in the string. So if the count is, say, 6? Find 6 numbers in a row. Does that make sense?
