 Sets can take their contents from an iterable and let you iterate over the set's

 all the whitespace from a stream of strings with the following code::

 You can select only certain elements by adding an ``"if"`` condition::
 
-    stripped_list = [line.strip() for line in line_list
-                     if line != ""]

 With a list comprehension, you get back a Python list; ``stripped_list`` is a
 list containing the resulting lines, not an iterator.  Generator expressions
