Hey Evan Mnatsekanov, the second task says "Now, write a function named numbers() that takes two arguments: a count as an integer and a string.". Your function numbers() only takes one argument. When the task checker runs, it provides two arguments, but only one is allowed by your code. This causes the error that you see.

It is your function that is not accepting the second argument. Please updated your numbers() function to accept a count as well as a string as the two arguments.

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

In three steps:

  • add a count parameter to the function signature line:
def numbers(count, fivenumbers):
  • use the count to define the repeated number
    return(re.search(r'\d' * count, fivenumbers))
  • notice that the typo / has been replaced with **

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