Your question is Optimize Memory Heavy Pandas Pipeline. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You're working on a Python data pipeline where a Pandas script is starting to fail as the input data grows. The job still works logically, but memory pressure is now the main bottleneck and makes the pipeline unreliable.
Walk me through how you would optimize a Pandas script that is currently running out of memory.
