How to replace just a part of a pattern in a text?

Question

Hi everyone!
I'm trying to edit a ".txt" file replacing the linebreaks in paragraphs with just spaces. I started with regular expressions like this:
pattern1 = r"(\D+\n)(a-z)"
If I'm not wrong this would match with every line break inside a paragraph, but then I would like to replace just the "\n" with " "
Somebody to help?

Answer 1

import re

Line = re.sub('regex', replacement, yourString)

Answer 2

.splitlines() method ignores "/n" when reading from a file. hope it helps
