bytecode is a Python module to generate and modify bytecode.

• bytecode project homepage at GitHub <https://github.com/MatthieuDartiailh/bytecode>_ (code, bugs)
• bytecode documentation <https://bytecode.readthedocs.io/>_
• 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 atdead-bytecode <https://github.com/p403n1x87/dead-bytecode>_ instead.

Example executing print('Hello World!'):

.. code:: python

from bytecode import Instr, Bytecode

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