Action Steps
  1. Use the yield keyword to create a generator in Python
  2. Apply the send() method to resume execution of a generator
  3. Test the difference between generators and iterators in a Python script
  4. Configure a class to use yield for lazy evaluation
  5. Compare the performance of generators and traditional iterators in a benchmarking test
Who Needs to Know This

Python developers and data scientists can benefit from understanding yield to write more efficient code, especially when working with large datasets or complex algorithms
