Use these tables to plan portfolio, lab, or self-study builds in Python. Start with basic scripts and small GUIs, move to intermediate APIs and automation, then advanced systems (queues, ML, distributed ideas). Each row: S. no., Project idea, Core idea, Small description (serial numbers 1–45 across all tables). Continue on Nikhil Learn Hub with Python simple projects, Python tutorial, and Java / back-end idea pages for comparison.
