Comparators in Python - Delft Stack

In our code, we first define the compare_absolute function, which takes two parameters, x and y.Inside this function, we use the cmp function to compare the absolute values of x and y.. The sorted function then uses this comparator to sort the numbers list. We pass the compare_absolute function to sorted using the cmp parameter.. Finally, we print the sorted list, which is sorted based on the ...

Sorting with a Comparator Function in Python 3 - DNMTechs
