10 Python Automation Scripts That Save Me Hours Every Week

I used to waste 3 hours a day on repetitive tasks Last year I was manually renaming files, checking APIs, parsing CSVs, and monitoring websites. Then I wrote 10 Python scripts that now run on autopilot. Here's the exact list — with working code you can copy right now. 1.
