ups, typo: ... that it will be helpful for more than one person :)I mean it is probably also possible to write a Python script version of most other pipe tools like wc, uniq, ... but it's still massively helpful to have those tools on hand everywhere you go. Don't get me wrong I'm not saying my program would be as useful as any of the coreutils. Compiling lists into ranges is a rarer use-case, but I had to implement these kinds of scripts often enough to be convinced, that I will be helpful for more than one person :)
