What are some common mistakes when using data structures in Python?

Some common mistakes include using mutable types as dictionary keys, not understanding list vs tuple differences, and misusing sets.

Can you explain why using mutable types as dictionary keys is a mistake?

Using mutable types like lists as dictionary keys can lead to unpredictable behavior since their hash value can change.

What about the difference between lists and tuples?

Lists are mutable, meaning they can be changed, while tuples are immutable, which makes them safer for fixed data.

How can I avoid these mistakes in my code?

You can avoid these mistakes by using immutable types for keys, choosing the right data structure for your needs, and reviewing your code for common pitfalls.
