A slot is nothing more than a memory management nicety: when you define __ slots__ on a class, you're telling the Python interpreter that the. Instead, all attribute access is done directly via pointers. Aside from being mutable and hence unhashable , byte arrays otherwise provide the same interface and functionality as immutable bytes objects. Sequences also support slicing: Some objects contain references to other objects; these are called containers. The recommended way of writing backwards compatible code in CPython 3.
