Tools: Web browser, Python (Pandas for CSV/Excel).
Why it's free & fast: The data is already collected, cleaned (to some extent), and ready for download. You just need to find the right one for your project.
Mohadevpur/Bangladesh relevance: You can often find datasets on global topics or even regional data on these platforms that are relevant to local challenges (e.g., climate data for agriculture, education statistics).
How to do it: Identify a website with publicly accessible, structured dataset data (e.g., a Wikipedia table, sports statistics sites, product listings from non-e-commerce sites that permit scraping). Use Python libraries like BeautifulSoup or Scrapy to extract the data into a CSV or Pandas DataFrame.
Time commitment: 4-8 hours (depending on website complexity and your coding speed).
Tools: Python (requests, BeautifulSoup/Scrapy, Pandas).
Ethical considerations: ALWAYS check the website's robots.txt file and Terms of Service. Be respectful, don't overload their server, and only scrape publicly displayed data. Avoid personal data.
Example: Scraping movie titles and ratings from a public movie database for a recommendation system prototype.
How to do it: Many services offer free public APIs (Application Programming Interfaces) for accessing their data, often with rate limits suitable for small datasets. Examples include public weather APIs, open movie databases (OMDB), social media (with strict API rules for non-personal data), or financial data APIs.
Time commitment: 3-6 hours (learning API documentation, writing scripts).
Tools: Python (requests, json), Postman (for testing API calls).
Ethical considerations: Adhere strictly to API usage policies, rate limits, and data usage terms.
Example: Collecting weather data for your local region in Mohadevpur from a free weather API to predict temperatures.
