When should I use lambda expressions?

What are lambda expressions and when should I use them?

Lambda expressions are anonymous functions that can be used to create small, one-off functions in your code. You should use them when you need a simple function for a short period, especially when passing functions as arguments.

Can you give me an example of where a lambda expression would be useful?

Sure! A common use case is with the map() function in Python, where you can apply a function to each item in a list. Instead of defining a separate function, you can use a lambda expression directly.

Are there any downsides to using lambda expressions?

Yes, while they are concise, lambda expressions can reduce code readability if overused or used in complex situations. It's important to balance brevity with clarity.

When should I avoid using lambda expressions?

Avoid using them when the function logic is complex or when you need to reuse the function multiple times. In such cases, a named function is clearer.
