Python | Reversing a Tuple

As we know that in Python, tuples are immutable, thus it cannot be changed or altered. This provides us with limited ways of reversing a tuple, unlike a list. We will go through few techniques on how a tuple in python can be reversed.
Examples:

```Input : tuples = ('z','a','d','f','g','e','e','k')
Output : ('k', 'e', 'e', 'g', 'f', 'd', 'a', 'z')

Input : tuples = (10, 11, 12, 13, 14, 15)
Output : (15, 14, 13, 12, 11, 10)
```

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Method 1: Using the slicing technique.
In this technique, a copy of the tuple is made and the tuple is not sorted in-place. Since tuples are immutable, there is no way to reverse a tuple in-place. Creating a copy requires more space to hold all of the existing elements. Therefore, this exhausts memory.

 `# Reversing a tuple using slicing technique ` `# New tuple is created ` `def` `Reverse(tuples): ` `    ``new_tup ``=` `tuples[::``-``1``] ` `    ``return` `new_tup ` `     `  `# Driver Code ` `tuples ``=` `(``'z'``,``'a'``,``'d'``,``'f'``,``'g'``,``'e'``,``'e'``,``'k'``) ` `print``(Reverse(tuples)) `

Output:

```('k', 'e', 'e', 'g', 'f', 'd', 'a', 'z')
```

Method 2: Using the reversed() built-in function.
In this method, we do not make any copy of the tuple. Instead, we get a reverse iterator which we use to cycle through the tuple, similar to the list.

 `# Reversing a list using reversed() ` `def` `Reverse(tuples): ` `    ``new_tup ``=` `() ` `    ``for` `k ``in` `reversed``(tuples): ` `        ``new_tup ``=` `new_tup ``+` `(k,) ` `    ``print` `new_tup ` ` `  `# Driver Code ` `tuples ``=` `(``10``, ``11``, ``12``, ``13``, ``14``, ``15``) ` `Reverse(tuples) `

Output:

```(15, 14, 13, 12, 11, 10)
```
