Splits a multiline string into a list of lines.

Use s.split() and '\n' to match line breaks and create a list.

str.splitlines() provides similar functionality to this snippet.

def split_lines(s):
  return s.split('\n')

split_lines('This\nis a\nmultiline\nstring.\n') # ['This', 'is a', 'multiline', 'string.' , '']
