Hacking with environment variables
>An unexpected exception to this is the antigravity module. The Python developers included an easter egg in 2008 which can be triggered by running import antigravity. This import will immediately open your browser to the xkcd comic that joked that import antigravity in Python would grant you the ability to fly.<p>> As for how the antigravity module opens your browser, it uses another module from the standard library called webbrowser. This module checks your PATH for a large variety of browsers, including mosaic, opera, skipstone, konqueror, chrome, chromium, firefox, links, elinks and lynx. It also accepts an environment variable BROWSER that lets you specify which process should be executed.<p>It was the possibility of security vulnerabilities that made software companies (more specifically Microsoft[0]) eschew easter eggs. Every feature, every line of code potentially increases your attack surface, especially if it interacts with other features.<p>0. <a href="https://docs.microsoft.com/en-us/archive/blogs/larryosterman/why-no-easter-eggs" rel="nofollow">https://docs.microsoft.com/en-us/archive/blogs/larryosterman...</a>
