What are generators in Python?

Answer

Generators in Python are a special type of function that return an iterator and allow you to iterate through a sequence of values lazily, meaning they produce values one at a time and only when requested. Instead of using return, generators use the yield keyword to return values. This makes generators memory-efficient, especially for large datasets, as they generate values on the fly rather than storing the entire sequence in memory.
