Hello, aspiring astronaut! Today, we're delving deeper into the universe of Python with a special emphasis on more complex built-in functions. We'll decipher the mysteries of map(), filter(), and zip(). Employing these functions can simplify our code, so fasten your seatbelts!

We begin with map(), a tool akin to a space probe that applies the same function on each item of a list. Here's how to utilize it: map(func, list). Let's apply it to double the numbers in a list:

Excellent work! With map(), we've doubled the items in our list.

Next up is filter(). It sifts out items based on a condition, acting like a cosmic patrol, filtering only those elements of the list that satisfy the provided condition (filter). It operates similarly to map(), except the function must return or . Let's extract the even numbers:
