What is the best way to reverse a string?

Björn Lindqvist,

This is one way that works in all Pythons.

>>> s = "some string"
>>> rev = s[::-1]
>>> print rev

In 2.4, a new builtin, reversed(), makes it so you can reverse a string
like this:

>>> s = "some string"
>>> rev = "".join(reversed(s))
>>> print rev

It can be especially useful when you want to iterate over a string in
reverse order:

>>> for x in reversed("some string"):
...     print x
