The "best way to do it" depends very much on what sort of data you're
trying to convert, and what you intend to do with the string once you
have it. (One could argue ;) that the "best way" would require *not*
using the name 'str' to store your string, since that will mask the name
of the builtin str() function -- which function might actually do what
you want, given the extremely vague description of your requirements.)

Pickle is intended to create a serialized version of an object, i.e. one
that can be saved to disk or sent through a network port and later
restored to active use. The fact that this serialized version is a
string is really just an implementation detail, though it's one that's
extremely unlikely to change.

If what you really want is a displayable string representation of your
object/tuple, you might be better off using str() or repr(), possibly
playing with the object's __str__() or __repr__() methods in order to
get it to display itself usefully. These won't necessarily let you
reconstruct the object from the string, but then you don't list that as
a requirement.
