In a Q&A, Python programming language creator Guido van Rossum said it was "almost taboo to talk about a Python 4 in a serious sense" following the troubled migration from Python 2.0 to Python 3.0.

Python isn't exactly boxed into high-end hardware, but that's where it's gravitated to and it's been left out of mobile and the browser, even if it's popular on the backend of these services, he said.
