This paper proposes a formalization to address this fragmentation. The central contribution is a formal foundation that uses concepts from type theory to demonstrate that Python's type system can be elegantly described. This work aims to serve as a crucial first step toward the future development of type inference tools.","short_abstract":"Python's typing system has evolved pragmatically into a powerful but theoretically fragmented system, with scattered specifications.
