Hi Suryapratap Singh Rathore! The challenge says "Write a function named first_number that takes a string as an argument.". So you solution will be of the form:

import re

def first_number(string):
    # your code here
    return your_results

In general, challenges that ask for a named function to be defined are expecting to call that function with various arguments to test to behavior of the function. In this case, it will pass in various strings to see if the results match expectations.

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