Python Return vs Yield: Memory-Efficient Generators

Ever wondered about the subtle difference between return and yield in Python? Here’s a tiny example that says a lot: def reg(): return "Hello World!!!" def gen(): yield "Hello World!!!" yield "My name is Raj" print(reg()) ==> # direct return res = gen() ==> # stores reference of gen function print(next(res)) ==> # first yield print(next(res)) ==> # resumes & gives next value return → gives you the result once and exits the function. yield → turns the function into a generator, producing values lazily (on demand). Why this matters: 1. Generators are memory-efficient 2. Perfect for large data streams or real-time processing 3. Backbone of iterators in Python 4. Functions can pause and resume execution (game changer) Small code. Big concept. #Python #Programming #Coding #Developers #Backend #SoftwareEngineering #100DaysOfCode
