Other people explained the list comprehension, but you might be confused about the unfortunate choice of 'file' as the name in this example. 'file' is a built-in as you remarked. It is allowed, but a bad idea, to use names that are the same as built-ins. Some people characterize this as shadowing the built-in. A similar, common case is when people use the name 'list' for a list object. They shouldn't. The example could have been written as: [f for f in files if f.endswith(extension)] -- http://mail.python.org/mailman/listinfo/python-list
