This is a medium-difficulty Python question that asks you to trace through a code snippet and predict its output. It is commonly used in technical interviews to assess how carefully you read code and whether you understand Python's semantics in practice.
Questions of this type reward precision: you must account for operator precedence, type coercion, built-in function behaviour, and any subtle language features at play. Rather than running the code mentally at high speed, strong candidates slow down, identify each operation step-by-step, and verify their assumptions about what Python will do. Interviewers use these problems to distinguish between candidates who have deep language familiarity and those who rely on guessing or pattern-matching.
