How do data structures affect performance in Python?

Data structures play a crucial role in Python performance. They determine how efficiently data can be stored, accessed, and manipulated.

Can you give examples of different data structures in Python?

Sure! Common data structures in Python include lists, tuples, sets, and dictionaries. Each has its own performance characteristics.

Which data structure is the fastest for lookups?

Dictionaries are generally the fastest for lookups due to their hash table implementation, allowing average O(1) time complexity.

What about memory usage? Are some data structures more memory-efficient?

Yes, for instance, tuples are more memory-efficient than lists because they are immutable and have a smaller memory overhead.

How can I choose the right data structure for my project?

Consider factors like the type of operations you'll perform (e.g., lookups, insertions), the size of the data, and memory constraints.
