The cleanest way I’ve seen for looping through a list in reverse is using Python’s built-in reversed()
function.
It doesn’t actually reverse the list in memory, it just returns an iterator that walks through it backwards.
So if you don’t need to modify the list and just want to loop:
for item in reversed(my_list):
print(item)
This is super readable, works on all sequences, and avoids creating a full reversed copy.
