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= """\ ... 2 3 5 7 11 13 17 19 23 29 ... 31 37 41 43 47 53 59 61 67 71 ... 73 79 83 89 97 101 103 107 109 113 ... 127 131 137 139 149 151 157 163 167 173 ... 179 181 191 193 197 199 211 223 227 229 ... """
Each line is a block of 10 numbers. We need to unblock the rows ...
