One possiblity is zemberek: https://github.com/ahmetaa/zemberek-nlp/blob/master/morphology/src/main/resources/tr/master-dictionary.dict

Zemberek has a binary version based on protocol buffers as well for pre processed attributes and fast loading. it should be possible to read it with python directly:
