Welcome back! In the previous lesson, you were introduced to the basics of currying and partial application in Python. Today, we'll take a step further and learn about advanced currying techniques. By the end of this lesson, you'll understand how to implement currying with multiple parameters in Python and appreciate the modular and reusable code it produces.

Currying can make your functions more flexible and easier to manage, especially in complex systems. We will cover advanced currying concepts, dissect an illustrative code example, and explain how to apply these techniques practically. Ready to dive in?

Before we get into advanced currying, let's quickly revisit the concept of basic currying. Currying is the process of transforming a function that takes multiple arguments into a series of functions that each take a single argument. This can help make your functions more modular and easier to reuse.

In basic currying, you might have seen a function like this:

Here, add is a curried function that takes an integer a and returns another function that takes an integer b and returns the sum of a and b. This makes it possible to create specialized functions like add5, which can later be used to add 5 to any integer.
