In Chapter 7, Additional Tuple Techniques, we used the enumerate() function to make a naive assignment of rank numbers to sorted data. We can do things such as pairing up a value with its position in the original sequence, as follows:
pairs = tuple(enumerate(sorted(raw_values)))
This will sort the items in raw_values in order, create two tuples with an ascending sequence of numbers, and materialize an object we can use for further calculations. The command and the result are as follows:
>>> raw_values = [1.2, .8, 1.2, 2.3, 11, 18] >>> tuple(enumerate( sorted(raw_values))) ((0, 0.8), (1, 1.2), (2, 1.2), (3, 2.3), (4, 11), (5, 18))
In Chapter 7, Additional Tuple Techniques, we implemented an alternative form ...
