What are some advanced functional programming techniques in Python?

Some advanced techniques include higher-order functions, decorators, and using the functools library.

Can you explain how decorators work in functional programming?

Sure! Decorators are functions that modify the behavior of another function. They allow you to wrap a function to extend its behavior without permanently modifying it.

How can I use lambda functions effectively?

Lambda functions are great for creating small, anonymous functions on the fly. They're often used with functions like map, filter, and reduce.

What is the role of the functools library?

The functools library provides higher-order functions that act on or return other functions, making functional programming easier in Python.

Can you give an example of using map and filter together?

Absolutely! You can use map to apply a function to all items in a list and filter to remove items that don't meet a condition. For example, list(filter(lambda x: x > 0, map(lambda x: x - 1, my_list))).
