Somehow the linebreaks are not working as they should. This is what I get:
Expected:
O meu u2 2 post
http://www.yahoo.com
1 Gosto, 0 Nao gosto
<BLANKLINE>
O meu u2 post
http://www.altavista.com
1 Gosto, 0 Nao gosto
Got:
'O meu u2 2 post\nhttp://www.yahoo.com\n1 Gosto, 0 Nao Gosto\n\nO meu u2\nhttp://www.yahoo.com\n1 Gosto, 0 Nao Gosto'
This is the code used in the function. The important parts should be the str and showRecentComments functions
class Comments():
def __init__(self, u=None, text='', link=None):
self.u = u
self.text = text
self.link = link
self.topo = None
self.fim = None
def __str__(self):
actual = self.topo
s = ''
if actual == None:
return None
while actual != None:
if actual.seg == None:
s += str(actual)
actual = actual.seg
else:
s += str(actual) + '\n' + '\n'
actual = actual.seg
return s
def add(self,comment):
if self.topo == None:
self.topo = comment
self.fim = comment
else:
comment.seg = self.topo
self.topo.ant = comment
self.topo = comment
def remove(self,comment):
actual = self.topo
if (self.topo == self.fim) and (self.topo == comment):
self.topo = None
self.fim = None
while actual!=None:
if actual == comment:
if self.topo==comment:
actual.seg.ant = None
self.topo = actual.seg
elif self.fim==comment:
actual.ant.seg = None
self.fim = actual.ant
else:
actual.seg.ant = actual.ant
actual.ant.seg = actual.seg
break
else:
actual = actual.seg
def countLike(self):
count = 0
actual = self.topo
while actual != None:
if len(actual.likeList) >= 1:
count += 1
actual = actual.seg
else:
actual = actual.seg
return count
def showRecentComments(self,n):
count = 1
actual = self.topo
sC = ''
if actual == None:
return None
while actual != None:
if count < n:
sC += str(actual) + '\n' + '\n'
count += 1
actual = actual.seg
elif count == n:
sC += str(actual)
count += 1
actual = actual.seg
elif count > n:
break
return sC

It looks like you're looking at the representation of the string, which will show you the newline characters as \n. If you print or write to e.g. stdout (sys.stdout.write(s)) the string instead, the newlines will be expanded.
