Currently -R overrides a non-zero seed value in PYTHONHASHSEED. The behavior changed in 3.7. Either the docs or the behavior need to be fixed. To repeat my previous example (this time in Windows):

    C:\>set PYTHONHASHSEED=37

    C:\>py -3.6 -c "print(hash('spam'))"
    -1810080452065497889
    C:\>py -3.6 -Rc "print(hash('spam'))"
    -1810080452065497889

    C:\>py -3.7 -c "print(hash('spam'))"
    -1810080452065497889
    C:\>py -3.7 -Rc "print(hash('spam'))"
    -7199637890859510937

    C:\>py -3.10 -Rc "print(hash('spam'))"
