Sorry for the delay, just spoted the question as unanswered.

You almost have it and are doing the right thing casting count to a string first, but next:

  1. You need the curly braces to specify the min length and leave the max lenght unset: {count,}
  2. Tou need to sort out your single quotation marks to correct the inline concatenation.
return re.findall(r'\w{'+count+',}', string)
