These are good points. I can sometimes feel that Python is more pointer-y (?) than people expect, with stuff like:

    a = {"one": 1, "two": 2 }
    b = a
    b["two"] = 99
    print(a["two"])

The above prints 99, since "b = a" does not copy the value (the dictionary) but just the reference to the value ("the pointer", kind of). This is surprising to some people.
