uncompyle6 is a cross-version Python bytecode decompiler that translates bytecode from Python 1.0 through 3.8 back into equivalent Python source code. It also supports fragment deparsing at bytecode offsets, which is used in debuggers and stack traces.

Use cases

• decompile python bytecode back to source code
• recover lost python source from .pyc files
• deparse bytecode fragments for stack traces
• decompile old python 2 bytecode
• analyze python bytecode in a debugger
• audit compiled python code

When to choose

• you need to decompile bytecode across many Python versions (1.0-3.8)
• you want fragment deparsing tied to bytecode offsets
• other decompiler forks fail on your bytecode version

When to avoid

• you need to decompile Python 3.9+ bytecode (use decompyle3 or other tools)
• you need a perfect, guaranteed source reconstruction
• you only need bytecode disassembly rather than source
