Sample text

Pop(0) else: raise StopIteration for i in MyIterator([0, 1, 2]): print(i) Running the preceding code prints the following output: 0 1 2 Again, the reason why we can loop over any instance of MyIterator is because it implements the iterator protocol by virtue of its __iter__ and __next__ methods; the former returns the object we iterate, and the latter method returns the individual elements of the sequence one by one. py", line 19, in __next__ raise StopIteration StopIteration We instantiate MyIterator, and then, in order to get its values, we call next() on it multiple times.

When we catch one of these, we simply clean up and quit. The body of the loop itself is pretty simple; we use a yield expression to fetch data (somehow) and store it in the variable text. Then, we simply check whether substring is in text, and if so, we whine a bit. The following snippet shows how we can use this coroutine in the interpreter: >>> from coroutines import complain_about >>> c = complain_about('Ruby') >>> next(c) Please talk to me! send('Test data with Ruby somewhere in it') Oh no: I found a Ruby again!

This is, of course, technically incorrect; a processor has one or more cores, and a computer has one or more processors as cores do not exist in isolation. Depending on the algorithm and its performance requirements, running on multiple processors or on a single processor using multiple cores can make a bit of difference in speed, assuming, of course, that the algorithm can be parallelized in the first place. For our intents and purposes, however, we will ignore these differences and refer to more advanced texts for further exploration of this topic.
