How Can I Iterate Over a Python List in Reverse Order?

Iterating Over Lists in Reverse Order

Navigating lists in the reverse direction is a common task in programming. In Python, you can achieve this using built-in functions and list comprehension.

Creating a Reversed List

To obtain a new list in reverse order, utilize the reversed() function. Combine it with list comprehension to collect the reversed elements into a new list:

xs = [0, 10, 20, 40]
reversed_list = list(reversed(xs))

reversed_list will contain [40, 20, 10, 0].

Iterating Backwards Through a List

For iterating over a list in reverse order without creating a new copy, employ the reversed() function directly:

for x in reversed(xs):
    print(x)

This code will print the elements of xs in reverse order:

40
20
10
0
