What are the best practices for using lambda expressions in programming?

When using lambda expressions, it's important to keep them concise and readable. Avoid complex logic within them.

Can you give me an example of a good lambda expression?

Sure! A simple example is using a lambda to sort a list of tuples by the second element: sorted(list_of_tuples, key=lambda x: x[1]).

Are there any performance considerations I should be aware of?

Yes, while lambda expressions can be convenient, they may introduce overhead if used excessively in performance-critical code.

How do lambda expressions compare to regular functions?

Lambda expressions are anonymous and can be defined in-line, making them useful for short, throwaway functions, while regular functions are named and reusable.
