Python for OSINT

Python for OSINT: 21-Day Course is a beginner-oriented training repository focused on automating repetitive open-source intelligence tasks with Python. It accompanies a free course PDF and provides sample code for lessons organized across three weeks. Topics progress from basic syntax and command-line tools to HTTP requests, APIs, JSON, CSV, databases, scraping, regular expressions, proxies, and file handling. Later lessons cover domain research, document generation, charts, maps, web archives, dates, and simple web applications. The course is designed for investigators and researchers rather than people seeking comprehensive software-engineering training. Exercises emphasize modifying working examples and applying them to practical research tasks. Current instructions recommend GitHub Codespaces or an Ubuntu-based environment for running the examples.
