What are the differences between lambda expressions and regular functions?

What are the differences between lambda expressions and regular functions?

Lambda expressions are anonymous functions defined with the lambda keyword, while regular functions are defined using def. They can be used interchangeably in some cases, but they have different use cases and syntax.

Can you give me an example of each?

Sure! A lambda expression could look like this: add = lambda x, y: x + y. A regular function would be defined as: def add(x, y): return x + y.

When should I use lambda expressions instead of regular functions?

Use lambda expressions for short, throwaway functions, especially when passing them as arguments to higher-order functions. Regular functions are better for more complex logic or when you need to reuse the function.

Are there any limitations to lambda expressions?

Yes, lambda expressions can only contain a single expression and cannot include statements or annotations, which limits their complexity.
