How do I choose key and value types in a dictionary?

What factors should I consider when choosing key and value types for a dictionary?

You should consider the data types you'll be storing, the operations you'll perform, and the performance implications.

Can you give me examples of suitable key and value types?

Sure! Common key types include strings and integers, while value types can be lists, sets, or even other dictionaries.

How do the key types affect the performance of the dictionary?

Key types can impact lookup speed and memory usage. For instance, integers are generally faster for lookups than strings.

Are there any best practices for using dictionaries in Python?

Yes! Use immutable types for keys, keep values simple, and avoid using large objects as values to maintain performance.
