return an re.search for exactly count integers in the string. They want me to count the # of integers?

They want me to count the number of integers that appear in the string, and return it? Or they want me to return the integers. E.g.) tasty44332 returns: 44332

or they want tast44332 to return: 5

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

Hey Cory Rhodes, given an int count and a str string, return the search object if there are count number of integers within the string. So, numbers(4, “abcde1234”) would return a valid search, but numbers(4, “abcde123”) would not.

Post back if you need more help. Good luck!!!
