Build a Fibonacci Sequence Generator

Level: Beginner

Your task for today is to create a Python generator that produces Fibonacci numbers on demand without storing the entire sequence in memory. Please use Python generators for this.

Project Task

Create a Fibonacci sequence generator that:

• Uses Python’s generator function with the yield keyword

• Generates Fibonacci numbers one at a time

• Allows users to specify how many numbers to generate

• Demonstrates lazy evaluation (generates values only when needed)

• Shows the memory efficiency of generators vs lists

• Prints each Fibonacci number as it’s generated

This project gives you hands-on practice with Python generators, the yield keyword, and memory-efficient iteration — essential skills for working with large datasets and infinite sequences.
