Treehouse Moderator 68,457 PointsThe challenge asks you to create a function called first_number. You’ve created a named variable instead.
The error Bummer: TypeError: search() missing 1 required positional argument: 'string' refers to the search method that takes two arguments, the pattern and a string to apply the pattern to.
Your function will take one argument. This argument will be the string to use in the search call.
Also, in the pattern, the r should prefix the string, and not be inside the string.
Post back if you need more help. Good luck!!!
