It's called a list comprehension. You can see some examples here: http://docs.python.org/tut/node7.html#SECTION007140000000000000000 It won't work with your example though - 'print' is a statement, not an expression, and cannot be used in a LC. You could use sys.stdout.write(name + '\n') instead if you like. Personally I think it is bad style to use a LC for its side effects; in those cases I prefer to write the loop out.
