Hey Mircea Dumitrescu, turns out you’re very close!

  • a function needs to return a value. Without a return statement a function has default return None. :point_right: replace print with return
  • the findall method returns a list and not a search result object. A list has no group method. :point_right: replace findall with search

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