The purpose of RAII is not to be an alternative to garbage collection
(which the those answers imply), but to ensure  deterministc execution of
setup and tear-down code. The Python equivalent of RAII is not garbage
collection but context managers.

Those answers is a testimony to how little the majority of C++ users
actually understand about the language.



A C++ statement with RAII like

{
   Foo bar(); 
   // suite
}

is not equivalent to

    bar = Foo()

in Python. It actually corresponds to

with Foo() as bar:
    <suite>
