Generators in Python are literators they produce data one element at a time. Generators are memory efficient. They don’t store the entire sequence upfront, making them ideal for large datasets. This emphasizes its ability to handle potentially infinite or very large sequences without memory limitations.
They are created using a special kind of function known as the generator function, which contains one or more ‘yield’ statements. The yield statement produces a value and temporarily suspends the generator function's execution, allowing it to be resumed later.
