Python Coding challenge - Day 499| What is the output of the following Python Code?

Code Explanation:

Line 1: Function Definition

def weird_add(x):

Defines a function weird_add that takes one argument x.

Line 2: Returning a Curried Function

    return lambda y: lambda z: x + y + z

weird_add returns a lambda that takes y, which in turn returns another lambda that takes z.

The final computation is x + y + z.

This is an example of currying, where you break a function with multiple arguments into a chain of single-argument functions.

Line 3: Function Call Chain

print(weird_add(1)(2)(3))

Let's evaluate this step by step:

Step 1: weird_add(1)

Returns:

lambda y: lambda z: 1 + y + z

Step 2: ... (2)

This becomes:

lambda z: 1 + 2 + z

Step 3: ... (3)

Now we compute:

1 + 2 + 3 = 6

 Final Output:

6
