Still do not get how Python iterates over a file

[Gribouillis]

In this problem, 'Matched' and 'Not Matched' have a different status: you want to print 'Matched' if AT LEAST ONE of the elements of list_2 corresponds to el, and you want to print 'Not Matched' if NONE OF THE elements of list_2 corresponds to el. We don't see this dissymetry in the code.
