This is a medium-difficulty Python question that asks you to read and predict the output of a code snippet. It rewards careful attention to language semantics, variable scope, and the order of execution—skills that matter in both interview settings and production work.
To solve problems like this, you need to step through the code mentally, tracking how variables are assigned and modified at each stage, and how control flow affects which statements run. The goal is not just to guess the output, but to demonstrate that you understand why the code behaves the way it does.
