Using Iterators in Pythonland

Day 1 – Learning Iterators and Iterables in Python

Today on DataCamp, I explored some core Python concepts:

• iter() function → Used to create an iterator from an iterable (like a list, tuple, or string).

• zip() function → Combines two or more iterables element-wise into tuples.

• range() function → Generates a sequence of numbers, commonly used in loops.

• next() function → Retrieves the next element from an iterator.

I also learned the key difference between:

• Iterable: An object that can return one of its elements at a time (e.g., list, tuple, string).

• Iterator: An object that represents a stream of data, produced by functions like iter(). You can use next() on it until it’s exhausted.
