* `Download latest bytecode release at the Python Cheeseshop (PyPI)
  <https://pypi.python.org/pypi/bytecode>`_

Install bytecode: ``python3 -m pip install bytecode``. It requires Python 3.8
or newer. The latest release that supports Python 3.7 and 3.6 is 0.13.0.
The latest release that supports Python 3.5 is 0.12.0. For Python 2.7 support,
have a look at `dead-bytecode <https://github.com/p403n1x87/dead-bytecode>`_
instead.

Example executing ``print('Hello World!')``:

.. code:: python

    from bytecode import Instr, Bytecode

    bytecode = Bytecode([Instr("LOAD_GLOBAL", (True, 'print')),
                         Instr("LOAD_CONST", 'Hello World!'),
                         Instr("CALL", 1),
                         Instr("POP_TOP"),
                         Instr("LOAD_CONST", None),
                         Instr("RETURN_VALUE")])
    code = bytecode.to_code()
    exec(code)
