Applied Questions

Q25. You work as an operations manager at a logistics company. Every week, you receive 8 spreadsheet files from your regional depots. You manually combine them to create a shipping performance dashboard.

Using the ROI framework from Chapter 1: - Estimate a reasonable automation setup cost in Python-work hours - Estimate the weekly time savings - Calculate the break-even point in weeks - Describe one non-time benefit of automation in this scenario

True or False: Q11: False (named after Monty Python's Flying Circus) Q12: True Q13: False (the goal is "capable business Python practitioner," not software engineer) Q14: False (Python is recommended for business professionals wanting broad coverage) Q15: False (if Priya is sick, no one else can do it correctly — this is explicitly a knowledge dependency risk) Q16: True Q17: True Q18: False (described as the hardest) Q19: True (3 hours/month × 12 months = 36 hours) Q20: False (Python complements SQL; they're used together)

Short Answer — Sample Responses:

Q21: Difficulty refers to inherent complexity that doesn't diminish with practice. Unfamiliarity is the discomfort of encountering something new, which naturally decreases as you practice. Python feels hard at first because it's unfamiliar, not because it's inherently complex.

Q22: (1) Acme Corp — a mid-sized regional distributor of office supplies with ~200 employees where analyst Priya Okonkwo generates manual reports. (2) Maya Reyes — a freelance business consultant who tracks projects and invoices in disconnected spreadsheets.

Q23: When analysis takes minutes instead of hours, professionals run more analysis, test more hypotheses, and ask questions they wouldn't have asked if they were expensive. It changes both work speed and thinking breadth. It's underrated because it's harder to quantify than time savings.

Q24: Any three of: readable, practical, huge business ecosystem, free and open source.

Applied (Q25 — Sample): Setup cost: 6–10 hours. Weekly time savings: 1.5 hours. Break-even: 4–7 weeks. Non-time benefit: The script runs identically every week, eliminating copy-paste errors and inconsistent formatting — improving the reliability and trustworthiness of the dashboard.
