reversed vs [::-1]
Note that reversed() doesn't return a list, it returns an iterator. Your code snippets aren't equivalent. Should programmer choose carefully between slicing and reversed? Only if you have huge lists that take up gigabytes of memory. Just choose the one that expresses your intent more clearly. More on reddit.com

January 16, 2024why reversed (list) is iteratorable but list.reverse() is not?
Basically because the reverse() function has a return type of None, it modifies the list in place. It's a call to a function, not to the list itself. Just like you couldn't do reversed_list = list.reverse(), because reversed_list would hold the value of None (But the list variable would still be reversed in-place). Where list[::-1] is a call to the list itself, with instructions on how to iterate through it. More on reddit.com

August 26, 2024Why does [::1] reverse a string in Python?
On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge. If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options: Limiting your involvement with Reddit, or Temporarily refraining from using Reddit Cancelling your subscription of Reddit Premium as a way to voice your protest.

Reverse Strings in Python: reversed(), Slicing, and More – Real Python
July 31, 2023 - In this example, you apply the slicing operator on greeting to create a reversed copy of it. Then you use that new reversed string to feed the loop. In this case, you’re iterating over a new reversed string, so this solution is less memory-efficient than using reversed(). If you’ve ever tried to reverse a Python list, then you know that lists have a handy method called .reverse() that reverses the underlying list in place.

Line 4: We call the reverse() method on the list. Line 6: We print the updated list. The slicing method works on iterables in Python and we exploit this to our advantage. However, the original list remains unchanged because a shallow copy is created in slicing.
