How to Reverse the Order of Objects

The reversed function reverses the order of iterable objects like lists.

The reversed function creates a new iterator with the elements in reverse order without modifying the original list.

An iterator is an object that allows you to traverse through all the elements in a collection (e.g., list, tuple, string) sequentially. It has a next() method that returns the next element.

Copy
numbers = [1, 2, 3, 4, 5]

# Create a new iterator with the elements of numbers in reverse order
for number in reversed(numbers):
    print(number)
# Output: 5, 4, 3, 2, 1

The reversed function is used to reverse the order of elements in objects like lists or strings, or to handle elements in reverse order within loops.

Copy
numbers = [1, 2, 3, 4, 5]
reversed_list = list(reversed(numbers))

print("reversed_list:", reversed_list)
# [5, 4, 3, 2, 1]
