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!!
