Python provides two common ways to reverse a list:

1. reverse() method (modifies the list in-place)
2. reversed() function (returns a reversed iterator)

Each has its own advantages depending on the use case.

1. reverse() Method (In-Place Reversal)

• Works only on lists.
• Modifies the original list directly (in-place).
• More memory-efficient since it doesn’t create a new list.

Example:

my_list = [1, 2, 3, 4, 5]
my_list.reverse()  
print(my_list)  # Output: [5, 4, 3, 2, 1]

✔️ Use reverse() when you want to modify a list without creating a new list.

2. reversed() Function (Returns an Iterator)

• Works with any iterable (lists, tuples, strings, etc.).
• Returns a reverse iterator, which can be converted to a list or used in a loop.
• Does not modify the original iterable.

Example:

my_list = [1, 2, 3, 4, 5]
reversed_list = list(reversed(my_list))  
print(reversed_list)  # Output: [5, 4, 3, 2, 1]

✔️ Use reversed() when you need a new reversed list while keeping the original intact.

Choosing Between reverse() and reversed()

✔️ Use reverse() when you need an in-place modification of a list.
✔️ Use reversed() when you need to reverse any iterable without modifying the original data.

Summary

Both reverse() and reversed() provide flexibility:

• reverse() is best for modifying a list directly.
• reversed() is best for working with any iterable while preserving the original.

Choose based on whether you need in-place modification or a new reversed version. 🚀
