python-like style

[Mike C. Fletcher]

Here's another approach:

 >>> file = open( somefile ).readlines()
 >>> keyword = '('
 >>> [ file[i+1]
	for i in range(len(file)-1)
	if keyword in file[i]
]

The problem with your code is that, as the error notes, 's' is not 
defined, you also seem to be using the iterator as both a string 
representing the last result, and an object matching the iterator 
protocol.  As far as I know, that doesn't work, but then, I've not yet 
used an iterator in my own code :) .

HTH,
