Finding definitions from a source file and a line number in Python

This article details a Python programming challenge: determining the enclosing function, method, or class for a given line number in a source file. It explains why simple parsing is insufficient and presents a robust solution using Python's `ast` and `tokenize` modules to correctly handle file encoding and traverse the Abstract Syntax Tree to find the closest definition.
