You could use exec (potentially dangerous if not all code being exec-ed is
under your control):

>>> f = 'foo'
>>> b = 'bar'
>>> exec '%s = b' % f
>>> foo
'bar'

You could also manipulate the globals or locals dictionary:

>>> globals()[f] = b*2
>>> foo
'barbar'
>>> locals()[f] = b*3
>>> foo
'barbarbar'
