the variable "count" is not being recognized as a variable and so I'm not getting the right output
import re
# EXAMPLE:
# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']
def find_words(count, string):
return re.findall('\w{count,}', string)

As written the letters “count” are going to be seen as a string. The variable needs to be evaluated as an integer before incorporating it into the string.
The hard part is that most formatting syntaxes use the curly brackets as field identifiers and may be confused by the regex count specifier.
To signify to keep (or escape) a literal curly bracket, instead of using it as a field identifier, use a doubled curly brace. This means you might see three in a row: two for the literal curly brace and on for the field marker.
So if you convert your regex into an f-string it would look like:
f'\w{{{count},}}'
# LLF F LL
# L marks Literal curly bracket
# F marks field curly bracket
Post back if you need more help. Good luck!!!
