returns an iterator that accesses the given sequence in the reverse order.

CODE 1

 `# Python code to demonstrate working of``# reversed()`` ` `# For string``seqString ``=` `'geeks'``print``(``list``(``reversed``(seqString)))`` ` `# For tuple``seqTuple ``=` `(``'g'``, ``'e'``, ``'e'``, ``'k'``, ``'s'``)``print``(``list``(``reversed``(seqTuple)))`` ` `# For range``seqRange ``=` `range``(``1``, ``5``)``print``(``list``(``reversed``(seqRange)))`` ` `# For list``seqList ``=` `[``1``, ``2``, ``4``, ``3``, ``5``]``print``(``list``(``reversed``(seqList)))`

Output :

```['s', 'k', 'e', 'e', 'g']
['s', 'k', 'e', 'e', 'g']
[4, 3, 2, 1]
[5, 3, 4, 2, 1]
```

CODE 2

 `vowels ``=` `[``'a'``, ``'e'``, ``'i'``, ``'o'``, ``'u'``]`` ` `# Function to reverse the list``def` `__reversed__(``self``):``    ``return` `reversed``(``self``.vowels)`` ` `# Main Function    ``if` `__name__ ``=``=` `'__main__'``:``    ``print``(``list``(``reversed``(vowels)))`

Output :

```['u', 'o', 'i', 'e', 'a']
```
