Parallel Assignment

What this Python parallel assignment question tests

This is an easy language-knowledge question that probes your understanding of how Python evaluates simultaneous assignments. It's the kind of question interviewers ask to confirm you have solid mental model of Python's evaluation order and object semantics—skills that matter when debugging production code or reasoning about state changes in a live system.

Questions like this reward careful reading of operator precedence and the exact sequence in which Python evaluates and binds values. Many candidates rush and miss subtle details about whether names are resolved left-to-right, right-to-left, or all at once. The point is not trick you, but to verify you can confidently predict what a short, idiomatic Python snippet will do.

• Python's tuple unpacking and assignment semantics
• Order of evaluation in compound assignment statements
• Reference vs. value in Python object binding
