Скачать или смотреть Python Interview Trick: The Mutable Default Argument Gotcha 🚨

Think you know Python functions? 🤔
This interview-style Python question will blow your mind! 💡
In this short, we’ll explore one of the most common gotchas in Python — mutable default arguments.
Watch as a simple function keeps adding values to the same list across multiple calls.

🔑 Key Takeaways:

Default arguments in Python are evaluated once, not every time.

Mutable objects like lists or dictionaries can lead to unexpected behavior.

Best practice: use None as the default and create a new list inside the function.

Perfect for Python interviews, coding challenges, or just leveling up your Python knowledge! 🚀
