A few years ago I came across that, and raised it on the bug tracker. The core devs decided that the backwards compatibility promise only applies to the output of random.random() itself, not the assorted other methods. If you care about the specific sequence of pseudo-random numbers generated by a particular method across versions, you have to use your own implementation. You can trust that random.random()'s output alone will be reproducible, anything more than that you have to manage yourself. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
