    Disassemble the *x* object.  *x* can denote either a module, a class, a
    method, a function, a generator, a code object, a string of source code or
    a byte sequence of raw bytecode.  For a module, it disassembles all functions.

-   raw bytecode, it prints one line per bytecode instruction.  Strings are first
-   compiled to code objects with the :func:`compile` built-in function before being

    The disassembly is written as text to the supplied *file* argument if
