Python regular expressions

Not sure what’s wrong with my code. My error message says it’s getting a nested list output ([[]]).

word_length.py 
import re

# EXAMPLE:
# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']
def find_words(count,starg):
    string_search=re.findall(r'\w{count,}', starg)
    string_list=[]
    string_list.append(string_search)
    return string_list

You won't need to nest string_search inside another string, you can return it directly.

But you also don't want the word "count" as part of your regex. Instead, use concatenation or formatting to include the value of the count in the regex.
