I'm not sure exactly what string representation of a dictionary you use.
But it's not too hard to use dict().  E.g.:

  >>> d = '''
  ... a:b
  ... c:d
  ... e:f
  ... '''
  >>> dict([x.split(':') for x in d.split()])
  {'a': 'b', 'c': 'd', 'e': 'f'}

Or:

  >>> dct = "{'a': 'b', 'c': 'd', 'e': 'f'}"
  >>> dict([map(str.strip, x.split(':'))
  ...       for x in dct[1:-1].replace("'",'').split(',')])
  {'a': 'b', 'c': 'd', 'e': 'f'}
