I have yet to have a python versioning issue, but with java I've had tons.

Worst of all, it's always a clear "use the latest version and it will work". With python using the latest version almost always works, and you can import the previous functions if you really want to use the new interpreter on old code.

Maybe this is because most of the time with python you barely have external libraries. Similar to Java, but in Node.js it's like asking for trouble.
