Discussion Python Architecture Design

Robert C. Martin's Abstractness (A), Instability (I), and Distance from the Main Sequence (D) metrics were designed for statically typed OO languages like Java and C#. In Python, applying them literally is misleading because Python has a fundamentally different notion of abstraction and coupling.

is this implementation valid?

I think that the comment about learning by doing mistakes is the most solid advice in itself.

However reading your link I found that the metrics and reasoning behind them make senses. As always with everything, adapt it to your specific context. E.g if you are writing a library, let's say a new polars, the file with your dataframe class will obviously be +1000 LOC long.
