library0.1.3pypypi✓ verified 85d ago

dis3 is a backport of Python 3.5+'s `dis` module to Python 2.7. It provides the inspection and bytecode disassembly functionality of CPython 3.5+ on legacy Python 2.7. Current version: 0.1.3. Release cadence is slow, primarily for compatibility use cases.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

dis

✓ from dis3 import dis

Import directly from dis3 to avoid shadowing the stdlib module.

Basic usage: import dis from dis3 and use it on a function to see bytecode instructions.

from dis3 import dis from dis3 import Bytecode, Instruction, CodeInfo def example(): x = 1 y = 2 return x + y dis(example)

Debug

Known issues

gotchaInstalling dis3 on Python 3 will import the stdlib `dis` but with version-based branching; it is designed for Python 2.7, not Python 3. Use the stdlib 'dis' on Python 3.

fix

Only use dis3 on Python 2.7. On Python 3, use `import dis` directly.

affects: all

deprecatedThe `CodeInfo` class and some instruction attribute names changed between Python versions; dis3 may not perfectly emulate Python 3.5+'s API in all edge cases.

fix

Test thoroughly if relying on specific bytecode attributes.

affects: 0.1.3

gotcha`Bytecode` class may have different iteration behavior than stdlib due to differences in Python 2 vs 3 bytecode.

fix

Refer to Python 2.7 dis documentation for expected behavior differences.

affects: all

Errors

Common errors & fixes

ImportError: No module named 'dis3'

Package not installed or running on Python 3 where it is not needed.

fix

Run `pip install dis3` on Python 2.7. On Python 3, use the built-in `dis` module.
