Yes, simply:

     s = 'hello world'
     #    ^
     #    it is a *string literal*

     s  # <- it is a *string object*
        #    (or rather a name referring to it :-))

(In Python we have rather 'names' than 'variables', though -- as
a mental leap -- they are commonly referred to as 'variables',
regarding other languages' terminology).
