Version 1:
>>> w='erewr \r\nafjdskl '.replace(" ", "")
>>> w
'erewr\r\nafjdskl'
>>> w='erewr \nafjdskl '.replace(" ", "")
>>> w
'erewr\nafjdskl'
>>> w='word1 word2 \nafjdskl '.replace(" ", "")
>>> w
'word1word2\nafjdskl'
>>>
it replaces all spaces, not only the trailing whitespaces.
version 2:
>>> w = 'erewr \r\nafjdskl '.strip(" \t")
>>> w
'erewr \r\nafjdskl'
>>> w = 'erewr \nafjdskl '.strip(" \t")
>>> w
'erewr \nafjdskl'
>>> w = 'word1 word2 \nafjdskl '.strip(" \t")
>>> w
'word1 word2 \nafjdskl'
>>>
I found a solution (not the most beautiful, but for
my purpose sufficiently good.)
Given: a file has no mixed lineendings, so it is either
a dos or unix file (mac line endings not respected).
swin="erewr \r\nafjdskl "
sunix="erewr \nafjdskl "
Dos Line endings (at least on '\r' included)?
r is contents of a file:
helpchar = ''
if r.find('\r') != -1:
helpchar = '\r'
retrailingwhitespacelf = re.compile('(?<=\S)[ \t'+helpchar+']+$',
re.MULTILINE)
newtext, n = retrailingwhitespace.subn(helpchar, r)
if n > 1:
r = newtext
