Worked like a charm! Thanks a lot!

So match method here not only searched for the string representation
of the number but also convert it to integer as well?

r stand for retrieve the string here?

and group?

Wehn a regex searched a .txt file when is retrieving something for it
always retrieve it as string right? or can get it as a number as well?
