How do dictionary comprehensions perform compared to traditional methods?

Dictionary comprehensions are generally faster and more concise than traditional methods like loops. They can improve readability and performance.

Can you provide a performance comparison with some examples?

Sure! For instance, using a dictionary comprehension like {k: v for k, v in iterable} is often faster than using a loop to populate a dictionary.

What factors affect the performance of dictionary comprehensions?

Factors include the size of the input data, the complexity of the expression used, and the efficiency of the underlying data structures.

Are there any scenarios where traditional methods are better?

Yes, in cases where readability is more important than performance, or when dealing with complex logic, traditional methods might be preferable.
