It's not only that way in python, but in java too. So it seems that there is
a fundamental principle behind it: In a language that allows sideeffects,
these will actually happen.

If you're after side-effect free programming, I recommend using a functional
programming language like ocaml or haskell. In these, you can't mutate
objects at all, only recreate them and rebind them to new variables. This
prevents whole classes of errors - but of course it also introduces all
kinds of other constraints on your programming style, e.g. using monads and
so on.
