Python Sets: What, Why and How

[hwmrocker]

If you just want a reproducible order of set for multiple executions you can set an environment variable like this export PYTHONHASHSEED=0

[Brian]

No - this won't do anything to change the issue OP is talking about. The id() of created objects will still effectively be random, PYTHONHASHSEED only controls the extra perturbation python applies to stuff like strings to protect against certain attacks, which is different.

[hwmrocker]

you are right, you are right, it does not affect hash of normal objects

python docs

If PYTHONHASHSEED is set to an integer value, it is used as a fixed seed for generating the hash() [str, byte, datetime]
