I must be missing something:

>>> xlines = (line for line in open("new.data") if line.strip())
>>> xlines
<generator object at 0x6b648>
>>> xlines.sort()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'generator' object has no attribute 'sort'

What do you think?
