Welcome, explorer! Are you ready to venture into the realm of Python's built-in functions? These comprehensive tools can streamline your code, saving both time and effort. Our mission is to familiarize ourselves with some of Python's straightforward built-in functions. Let's embark on this journey!

Much like a built-in navigational system guiding astronauts, Python's built-in functions serve as accessible tools to navigate through coding tasks at any time. They operate as our guiding stars through the cosmic realm of programming.

Let's chart a course through Python's built-in functions:

The len() function: This function counts elements in a list, set, tuple, or any data structure, much like counting candies in a box:

The abs() function: Functioning like a device determining a spaceship's absolute distance in light years from a specific point in space, this function gives the absolute value of a number.

The round() function: Similar to rounding off estimated distances or times, this function rounds a number to the nearest integer.
