That's not what I get:

In [2]: data='''xxx.xxx.xxx.xxx:yyy
    ...: xxx.xxx.xxx.xxx:yyy
    ...: xxx.xxx.xxx.xxx:yyy
    ...: xxx.xxx.xxx.xxx
    ...: xxx.xxx.xxx.xxx
    ...: xxx.xxx.xxx.xxx:yyy'''.splitlines()

In [3]: for line in data:
    ...:     print line.split(':')[-1]
    ...:
    ...:
yyy
yyy
yyy
xxx.xxx.xxx.xxx
xxx.xxx.xxx.xxx
yyy
