A function that checks if the list is sorted

[DeaD_EyE]

The useful function itertools.pairwise was added to Python 3.10.

https://docs.python.org/3/library/iterto...s.pairwise

This isn't Pythonic: range(len(something))

from itertools import pairwise
from string import ascii_lowercase
from random import choice, randint


test_data = [
    [choice(ascii_lowercase) for i in range(5)],
    [i for i in ascii_lowercase],
    [randint(1, 10) for i in range(10)],
    [i for i in range(10)],
]


def is_sorted(iterable):
    for last, current in pairwise(iterable):
        if last > current:
            return False
    return True


# test
for data in test_data:
    print(f"'{'-'.join(map(str, data))}' is {'' if is_sorted(data) else 'not'} sorted")
