It can often be a good idea to create an adapter/pattern for string
substitutions. Then the wrapper can "massage" the dict values before
they go into the string.
Here only a simple version is needed though (untested).
class Wrapper:
def __getitem__(self, key):
return locals().get(key, globals[key])
'Some string sub %(some_var)s' % Wrapper()
