Note: Following cross-posted to python-list where it got queued due to
suspicious subject line.
I'm looking for suggestions on technique (not necessarily code) about
the most pythonic way to normalize vertical whitespace in blocks of
text so that there is never more than 1 blank line between paragraphs.
Our source text has newlines normalized to single newlines (\n vs.
combinations of \r and \n), but there may be leading and trailing
whitespace around each newline.
I can't follow that! Please provide a before and after example.
Approaches:
1. split text to list of lines that get stripped then:
a. walk this list building a new list of lines that track and ignore
extra blank lines
-OR-
b. re-join lines and replace '\n\n\n' wth' \n\n' until no more
'\n\n\n' matches exist
2. use regular expressions to match and replace whitespace pattern of
3 or more adjacent \n's with surrounding whitespace
3. a 3rd party text processing library designed for efficiently
cleaning up text
Thanks!
