Understanding Python's dis module and bytecode inspection

This is a medium-difficulty question about Python's introspection capabilities, specifically the dis module. It tests whether you understand how Python compiles functions to bytecode and can read low-level instruction sequences.

To answer, you need to know what the dis module does, what it outputs, and why understanding bytecode matters in performance-critical code. This skill is particularly relevant for engineers working on latency-sensitive systems or debugging unexpected function behaviour. The question requires you to reason about the relationship between source code and its compiled representation.
