what is wrong in this????

Please Explain why this is wrong

when I replace variable "i" with 4 then it gives the perfect result.

why "," are not included in words when they are stored in li. Like li should be = ["baby,", "dog,", "cat,", "balloon,"]

word_length.py 
import re

# EXAMPLE:
# >>> find_words(4, "dog, cat, baby, balloon, me")
# ['baby', 'balloon']
def find_words(i, st):
    li = re.findall(r"\w{i,}", st)
    return li

:point_right: Your letter "i" is just a letter inside the quotes.

To make the passed-in value appear you have to insert it into the string with format, or convert it to a string and concatenate it with the rest of the string:

    li = re.findall(r"\w{" + str(i) + ",}", st)

And the comma is not included in the character class represented by "\w", so it will not be part of the matching words.

Isn't Comma a Unicode character ?
