Flattening data while mapping

In Chapter 4, Working with Collections, we looked at algorithms that flattened a nested tuple-of-tuples structure into a single iterable. Our goal at the time was simply to restructure some data, without doing any real processing. We can create hybrid solutions that combine a function with a flattening operation.

Let's assume that we have a block of text that we want to convert to a flat sequence of numbers. The text looks as follows:

>>> text= """\

... """  

Each line is a block of 10 numbers. We need to unblock the rows ...
