Generators and iterators in Python provide a more memory-efficient and scalable way to work with sequences of data compared to using lists. Here are some key advantages of using generators and iterators:

  1. Memory Efficiency: Generators produce values on-the-fly and don’t store the entire sequence in memory at once. This is especially beneficial when dealing with large datasets or infinite sequences, as it avoids the need to load the entire dataset into memory.
  2. Lazy Evaluation: Generators use lazy evaluation, meaning they generate values one at a time as needed. This allows for efficient processing of data, particularly in scenarios where not all elements are required or when dealing with infinite sequences.
  3. Reduced Memory Footprint: Since generators generate values dynamically, they have a smaller memory footprint compared to lists. This is particularly advantageous when working with large datasets or when memory resources are limited.
  4. Iterative Processing: Iterators provide a clean and convenient way to iterate over a sequence of elements. They are especially useful in situations where you need to process elements sequentially, one at a time.
  5. Efficient Pipelines: Generators can be…
