Python Uncompyle6
python-uncompyle6 is a Python bytecode decompiler and reverse engineering tool designed to convert compiled bytecode files back into human-readable source code. It functions as a source code recoverer and bytecode disassembler, allowing for the analysis of internal program logic and the reconstruction of original language constructs.
The tool provides cross-version support, enabling the analysis and recovery of source code from bytecode created across multiple different versions of the Python interpreter. This allows it to operate as a cross-version bytecode analyzer that can interpret varied instruction sets regardless of the version used to run the tool.
Its capabilities cover bytecode analysis and program inspection, including the ability to list instructions with interpreted flags and operands. The system can reconstruct source code from entire files or specific fragmented segments, such as lambda bodies and list comprehensions, by mapping bytecode offsets to source fragments.
