Last breaking changes in Python were in Python3 Python (or at least the standard library) breaks quite often compared to some other more conservative languages. For example they recently 'broke' dataclasses somewhere between 3.8 and 3.11 by changing how initialisation of default values works and I had to fix some code. Last breaking changes in Python were in Python3 If you only stick to the core language, then yes. If you make use of a lot of the standard library that comes with python by default, then all bets are off.
