In current Python document (3.7 - 3.9) there is such statement in documentation of Integer Objects:

The current implementation keeps an array of integer objects for all integers between ``-5`` and ``256``, when you create an int in that range you actually just get back a reference to the existing object. So it should be possible to change the value of ``1``.  I suspect the behaviour of Python in this case is undefined. :-)

The last sentence is vague. It is irresponsible to write "I suspect" in documentation. And as the statements ahead has already clarified the sense that this is "a current implementation", the last sentence should be removed.

There's nothing wrong with a little wry humor in the docs, especially when the provide a little insight into the implementation.  It isn't irresponsible at all -- please avoid those pejoratives.

That said, I'll accept the patch because the sentence isn't necessary and has other issues (the statement makes more sense in the ctypes module where such changes are possible and it applies broadly to all immutable objects, not just pre-computed singleton integers).
