how can I pass the argument count into the re function?

how can I pass the argument count into the function?

import re

EXAMPLE:

>>> find_words(4, "dog, cat, baby, balloon, me")

['baby', 'balloon']

def find_words(count, str1): print( re.findall(r'\w{count,}', str1))

find_words(4, "dog, cat, baby, balloon, me")

word_length.py 
import re

# EXAMPLE:
# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']

def find_words(count, str1):
  print( re.findall(r'\w{count,}', str1))

Here's a few hints:

  • just define the function, don't call it (the challenge does that itself)
  • remember to return the result, not print it
  • using the word "count" in the re string won't work, but building the string using the variable will
  • remember to convert the number into a string before concatenating with other strings

I'll bet you can get it now, but if you're still stuck...   <button' onclick='$("#spoiler").slideDown("slow");$(this).remove()'>Press to Reveal Spoiler</button> <div id='spoiler' style='display:none'>

:warning: SPOILER ALERT

def find_words(count, str1):
  return re.findall(r'\w{' + str(count) + ',}', str1)

</div>

Thank you Steven, it works as expected. It's a good idea to use str(count) to return it to raw string. :)
