You can't, because strings are immutable. Put it in a class or so and give
the class a method to change its string. Then let foo and bar be the same
instance.

class ChangingString:
   def __init__(self, s):
      self.s = s

foo = ChangingString('Hello')
bar = foo
bar.s = 'Whee'
# foo.s == 'Whee' now
