python3-bytecode 0.13.0-2 (amd64 binary) in ubuntu lunar

 The bytecode module can be used to write Python bytecode directly and
 then convert it into an executable Python code object. It also provides a
 pure Python implementation of the Peephole Optimizer introduced in
 CPython 3.6.
 .
 This module is patched to be compatible with python3-pydevd, but this
 should be transparent to other users.
