Iterable vs Iterator: The Critical Distinction Most Python Developers Get Wrong

1. 1Define a class that implements the __iter__ method to create an iterator
2. 2Use the iter() function to create an iterator from an iterable
3. 3Implement the __next__ method to control the iteration process
4. 4Test the iterator with a for loop to ensure it works as expected
5. 5Avoid making a class its own iterator to prevent silent failures in loops

Python developers and data scientists can benefit from this knowledge to write more efficient and effective loops

💡 An iterable is an object that can be looped over, while an iterator is an object that keeps track of its position in the loop
