Python’s iterators and functional programming features offer a powerful combination for writing concise, readable, and efficient code. Let’s explore how these concepts work together and how you can leverage them in your projects.

Iterators: The Building Blocks

An iterator is an object that allows you to traverse through a sequence of data, one element at a time. In Python, many built-in data structures, such as lists, tuples, and strings, are iterable, meaning you can loop over them using a for loop or access their elements one by one using an iterator.

Here’s a simple example of using an iterator:

my_list = [1, 2, 3, 4, 5]
iterator = iter(my_list)

print(next(iterator))  # Output: 1
print(next(iterator))  # Output: 2

Iterators are memory-efficient because they don’t load the entire sequence into memory at once. Instead, they retrieve elements as needed, making them ideal for processing large datasets.

Functional Programming: Transforming Data

Functional programming is a programming paradigm that emphasizes the use of pure functions, immutable data, and…
