Experience

  • Bytecode Tools
    https://github.com/gsb-eng/bytecode_tools

    These bytecode tools are a combination of multiple utilities to deal with Python bytecode; bytecode is generated by a Python compiler which is not consistent across versions.

    Understanding bytecode with standard library utilities is not straightforward across versions; these bytecode tools solve this problem with version-independent services to deal with the bytecode.
