left or right?

What this Python language-knowledge question tests

This is a medium-difficulty Python question that asks you to read and predict the output of a code snippet. It's the kind of question used to verify that a candidate has solid, practical knowledge of Python semantics rather than just theoretical understanding.

Questions like this often hinge on operator precedence, evaluation order, scoping rules, or the behaviour of built-in functions and data structures. The goal is to see whether you can trace through code mentally without running it—a skill that matters when debugging or reviewing code in a fast-paced environment.

• Operator precedence and associativity
• Order of evaluation (left-to-right vs. special cases)
• Built-in function behaviour and type coercion
• Python's scoping and name-binding rules
