Every language you will ever learn starts in the same place: making the computer say something. In both Lua and Python the tool for that is a function called print — you hand it a piece of text in quotes, and it appears in the output.
Task: make the program print exactly hello, world. Edit the code so it greets the world instead of the void, then press Run and Check.
Try the other language from the dropdown too — for this first step they are nearly twins.
