Chris -
In the Python 2.7.10 documentation, I am referring to section 5. Built-in
Types, subsection 5.9 File Objects.
In that subsection, I have the following paragraph:
file.read([*size*])
Read at most *size* bytes from the file (less if the read hits EOF before
obtaining *size* bytes). If the

Yes, I did understand that. In your example, "a" and "b" are the same pointer,
so an operation on one is an operation on the other (because they’re the same
memory block). My issue in Python came up because Python can dynamically
change one or the other to a different object (memory block) so

Sorry if you feel I'm being overly pedantic, but your explanatio
Chris,
Thanks for your reply.
I hope the evidence below (taken from IDLE) clarifies my issue:

All of these correctly show that a file, in binary mode, reads and writes bytes.

Thanks for your comments. After all, I asked for clarity so it’s not pedantic
to be precise, and you’re helping to clarify.
Going back to my original post,
mx1 = [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ]
arr1 = mx1[2]
Now if I write "arr1[1] += 5" then both arr1 and mx1[2][1] will be changed
I think the key point is that "the operation" doesn't act on "names" but
on "objects" (which are different sort of things), and thus there isn't
an "the other" when talking about the object being operated on.
Thinking of an operation being on a "name" is the mental model error.
The only operat

That's just window dressing. Pointers are evil, so we can't have
point
