Developer Releases V2 of Python Expense Tracker with Edit and Input Validation

A developer has released Version 2 of a personal expense tracker built using Python, OOP principles, SQLite, and SQL. The update adds an edit feature that allows users to modify existing expense details such as amount, category, description, and date. V2 also introduces comprehensive input validation to handle invalid menu choices, incorrect amounts, empty descriptions, and impossible dates like February 30. The project follows a layered architecture separating CLI flow, application logic, and database operations across three components. The developer noted that a key takeaway from this version was learning to define a clear scope and recognizing when a version is complete rather than continuously adding features.
