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_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()
