Problem set 5 in ocw.mit.edu programming science

Well, since there are several of those classes, some of which have more than one edition because they have more than one year, I'd need more than that.

Problem 3. Implement a word trigger class, TitleTrigger that fires when a news item’s title contains a given word. The word should be an argument to the class’s constructor. This trigger should not be case-sensitive (it should treat “Intel” and “intel” as being equal).


Each of the triggers listed there is "fired" when it matches something.  They are saying they want a whole word trigger that works on the titles.

@e.mccormick thanks for your reply. But I think I have great problems with this "class" stuff. I don't understand them so well and I can't understand the necessity of using them in some cases. Actually it really messed my mind.

A class is a template, a way to do things.  They are used in many languages for the creation of objects.  Python is not really an objective language, but it does have objective aspects, so the use of the term class and object is loosly applied.
