That looks expensive, esp. for objects implemented in Python — an extra dict entry plus a new unique int object. What is the problem you are trying to solve for these objects specifically? Just that the hex numbers look distracting doesn’t strike me as sufficient motivation.
Could the numbers be kept outside the object, perhaps in a weak* dictionary that's maintained in the __repr__ method, so you don't pay for it if you don't use it? *if the object's hash/eq use identity, anyway... a "weak identity-keyed dictionary" might be a nice thing to add anyway
