modified the test_generators.py to add more functions and enhanced code for learning, Thank you

This code provides a clear and well-structured set of Python generator functions demonstrating random number generation (for lottery-style draws) and Fibonacci sequence calculation. The functions are thoughtfully designed, with comprehensive docstrings explaining their usage, parameters, and expected behavior, which is very helpful for learners. Error handling is included to catch invalid arguments, making the code robust against incorrect usage. The inclusion of both a basic and a unique lottery generator shows an understanding of real-world lottery constraints, such as uniqueness of numbers. The fibonacci generator elegantly showcases how Python generators can handle potentially infinite sequences, and the test function thoroughly checks correctness for all implemented features. The code is readable, idiomatic, and suitable for educational purposes, and the example usage in the __main__ block provides practical demonstrations. Overall, this is a high-quality, instructional example for anyone learning about Python generators and basic testing practices.
