Project description

Latest release on the Python Cheeseshop (PyPI) Continuous integration Documentation building Code coverage of bytecode on codecov.io Code formatted using Black

bytecode is a Python module to generate and modify 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 instead.

Example executing print('Hello World!'):

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)
