Write Python Script to Scrape Product Reviews and Calculate Sentiment Scores
“Write a Python script that scrapes product reviews from an e-commerce site and calculates sentiment scores”
Summary · Write a Python script to scrape product reviews from an e-commerce site and calculate sentiment scores for each review.
AI produces a solid, runnable scaffold covering the core logic — HTTP requests, HTML parsing, and sentiment scoring — faster than any human alternative. However, site-specific selector tuning, JavaScript rendering, and anti-scraping workarounds require meaningful human intervention, preventing an 'excellent' rating. A reviewer with basic Python knowledge can close the gap in under an hour for most simple sites.
Where AI helps most
AI eliminates the boilerplate-writing and library-selection research that consumes most of a first-timer's time, cutting the iteration cycle from hours to minutes for the structural code.

Worker comparison
six profiles| Worker | Time | Cost | What you actually get | Conf. |
|---|---|---|---|---|
|
01
Solo Individual
DIY on your own time, no contract, no schedule
|
8–20 hours | $0 (self-done) but significant time investment | A first-timer will struggle with HTTP headers and anti-scraping measures, parsing inconsistent HTML, handling pagination, and wiring up a sentiment library like VADER or TextBlob. Expect multiple dead ends debugging requests being blocked, selector breakage, and misunderstanding polarity scores. Output will likely work on a single page but fail at scale or when the site changes structure. No error handling, no rate limiting, no retry logic. The script will be fragile and hard to maintain. | medium |
|
02
Solo Expert
Hire a freelance specialist, day rate, scoped per job
|
2–5 hours | $150–$500 (freelance rate $75–$120/hr) | A skilled Python developer with scraping experience will reach for the right tools quickly — BeautifulSoup or Playwright for rendering, VADER or transformers for sentiment, and proper session/header management. The main calendar risk is that even experienced freelancers on platforms like Upwork or Fiverr may need 1–3 days before starting. Scope creep is common: clients often discover mid-project that the target site is JavaScript-heavy or behind a login wall, which can double estimated hours. Revisions for output format or additional fields are typically limited to one or two rounds before extra charges apply. Vetting for genuine Python/scraping skill vs. copy-pasted demos requires real effort. | high |
|
03
Small Team
Coordinate 2 or 3 freelancers, handoffs and gaps
|
3–6 hours across the team | $300–$800 (blended team cost) | A team adds QA, code review, and the ability to split scraping and NLP work in parallel. Quality will be higher — modular code, error handling, and documented output schema are more likely. Coordination overhead is real but modest at this scope. Calendar time is typically 2–5 business days due to task handoffs and review cycles. Risk of misaligned assumptions about the target site structure or output format between members without a tight spec upfront. | medium |
|
04
Agency
Account-managed, billable hours, formal scope and SOW
|
4–8 hours billable (1–2 week delivery) | $600–$2,000 depending on agency tier and scope definition | An agency will deliver production-quality code with error handling, logging, configurable selectors, and clear documentation. However, engagement friction is significant: scoping calls, contracts, and onboarding typically add several days before any code is written. Agencies charge for project management overhead. Out-of-scope additions (e.g., proxies, authentication, cloud deployment) will trigger change orders. Budget creep is common if the site turns out to be harder to scrape than initially assessed. Refund exposure is low but disputes over deliverable definition do occur. | medium |
|
05
Enterprise
RFP, procurement, multi-stakeholder approvals
|
2–6 weeks elapsed (10–30 hours actual work) | $5,000–$20,000+ (internal cost including procurement, legal, IT review) | Enterprise execution introduces legal review of scraping terms-of-service, security review of outbound HTTP calls, procurement cycles, and IT approval for third-party libraries. The actual coding effort is modest, but approvals and compliance checks dwarf the development time. Output will be robust and auditable but vastly over-engineered for the underlying task. Internal teams may be resistant to building one-off scripts outside established data pipelines. | low |
|
AI
AI (Claude / Agent)
AI plus competent human review
|
20–60 minutes total (AI generation + human review and testing) | $0–$20 (API costs negligible; time cost of reviewer) | AI (Claude, GPT-4, Copilot) can produce a working first draft very quickly — imports, request headers, BeautifulSoup parsing, VADER sentiment scoring, and CSV output in one pass. However, realistic failure modes are significant: the generated selectors will almost certainly be wrong for any specific target site and must be manually corrected; JavaScript-heavy SPAs will require the human reviewer to swap in Playwright or Selenium; rate limiting and IP blocking are not handled by default. The human reviewer needs enough Python and scraping knowledge to identify and fix these gaps — perhaps 30–45 minutes of hands-on testing. For a generic, HTML-simple site this works well. For a major retailer with anti-bot measures, AI output is a starting scaffold, not a finished solution. | high |
