Python Generators & Iterators – What Makes yield So Powerful?
What happens when Python meets huge data files? Your laptop probably overheats—unless you use generators.
In this video I’ll show you:
Why a for loop already uses an iterator (and why lists don’t do the heavy lifting themselves)
How custom iterators give you total control—with __iter__() and __next__()
How generators—thanks to the magical yield keyword—let you skip the class-writing madness
When generators are the only sane way to process data—especially logs, CSVs, or 10GB files
A real‑world demo that reads a file line by line
And generator expressions, your new favorite memory‑shrinking one‑liner
👇 Challenge: Write a generator that processes something massive—log files, DB rows, sensor streams, or even the Fibonacci sequence—without dumping everything into RAM. Post your version below!
