How to answer these python interview questions

Python interview questions check language fundamentals and how clearly you explain tradeoffs. Say the behavior first, then a short example: mutability, identity vs equality, lazy vs eager evaluation. Practice with a Python interview quiz so you get a score and detailed feedback after each prompt. Strong answers name the rule, why it matters in production code, and one pitfall.

Sample python interview questions

Preview 6 questions from this track in quiz order. In the full quiz you answer one at a time — type or speak — then get a score and feedback.

  1. What is the difference between a list and a tuple in Python?

    What a strong answer includes

    Strong answer: lists are mutable and typically homogeneous sequences; tuples are immutable, hashable when contents are, and often used for fixed records.

  2. Explain the difference between `is` and `==` in Python.

    What a strong answer includes

    Strong answer: `==` compares value equality; `is` compares object identity (same object in memory). Mentions common pitfalls with interned small ints or None.

  3. Why is a mutable default argument (like `def f(x=[])`) a bug? How do you fix it?

    What a strong answer includes

    Strong answer: the default is created once at function definition and shared across calls. Fix with `None` as default and create a new list inside the function.

  4. How does a Python dict work, and what makes a good dict key?

    What a strong answer includes

    Strong answer: dicts are hash tables; keys must be hashable (immutable with a stable hash). Mentions average O(1) lookup and collision handling at a high level.

  5. When would you use a generator instead of returning a list?

    What a strong answer includes

    Strong answer: generators yield lazily, use less memory for large or infinite sequences, and are good for pipelines. Mentions `yield` vs building a full list.

  6. What is the difference between `@staticmethod` and `@classmethod`?

    What a strong answer includes

    Strong answer: staticmethod gets neither instance nor class; classmethod receives the class (`cls`) and is useful for alternate constructors.

Python interview quiz FAQ

Common questions about practicing python interview questions with a scored quiz.

What Python interview questions should I practice?

Practice lists vs tuples, `is` vs `==`, mutable defaults, dict keys/hashing, generators, staticmethod vs classmethod, `*args`/`**kwargs`, and context managers.

Should I write code or explain my approach?

Do both when you can. Interviewers often care about the mental model and edge cases as much as perfect syntax. A quiz helps you rehearse clear explanations under a score.

Is the Python interview quiz free?

You can start the Python track free. The first 2 questions include speech tools, scoring, and detailed AI feedback. Subscribe to finish the track and keep your progress.

How is this different from a mock AI interviewer?

This is a structured quiz: one question, your answer, a score and feedback. It does not open a free-form conversation with follow-up questions.
