February 23, 2026 - The partial() function can reduce the arity of a multi-argument function making it suitable for use as a key-function. >>> from functools import partial >>> from unicodedata import normalize >>> names = 'Zoë Åbjørn Núñez Élana Zeke Abe Nubia Eloise'.split() >>> sorted(names, key=partial(normalize, 'NFD')) ['Abe', 'Åbjørn', 'Eloise', 'Élana', 'Nubia', 'Núñez', 'Zeke', 'Zoë'] >>> sorted(names, key=partial(normalize, 'NFC')) ['Abe', 'Eloise', 'Nubia', 'Núñez', 'Zeke', 'Zoë', 'Åbjørn', 'Élana']

For more complex sorting like sorting by last name then by first name, you can use the itemgetter or attrgetter functions like: from operator import itemgetter # (first name, last name, score) tuples grade = [('Freddy', 'Frank', 3), ('Anil', 'Frank', 100), ('Anil', 'Wang', 24)] sorted(grade, key=itemgetter(1,0)) # [('Anil', 'Frank', 100), ('Freddy', 'Frank', 3), ('Anil', 'Wang', 24)] sorted(grade, key=itemgetter(0,-1)) #[('Anil', 'Wang', 24), ('Anil', 'Frank', 100), ('Freddy', 'Frank', 3)]

Let's try to do the sorting manually, just to get an even better understanding of how Merge Sort works before actually implementing it in a Python program. Step 1: We start with an unsorted array, and we know that it splits in half until the sub-arrays only consist of one element. The Merge Sort function calls itself two times, once for each half of the array.
