Lazify
Lazify all the things!
What it is and what it does
Lazify is a library for lazy evaluation in Python, originally derived from Babel's LazyProxy class. It aims to provide a comprehensive toolkit for deferred computation and lazy object handling, allowing you to defer expensive operations until their results are actually needed.
The package has no external runtime dependencies, making it lightweight to install. However, it has not seen a release since 2018, though the repository remains active. The library is positioned as a general-purpose lazy evaluation toolkit, but the fact sheet does not detail what specific lazy patterns or proxy mechanisms it exposes beyond its Babel heritage.
Use it for:
- Defer expensive computations in application startup or initialization paths until values are actually accessed.
- Wrap objects in lazy proxies to delay resource allocation until first use.
- Implement lazy loading in frameworks or libraries that need to avoid circular imports or early binding.
- Build lazy evaluation chains where intermediate results are only computed when downstream code requests them.
Worth the install?
AI-flagged interpretation of the facts on this page — verify before relying
Lazify provides lazy evaluation utilities for Python, enabling deferred computation and proxy-based lazy object handling.
Yes, if you need lazy evaluation utilities and are comfortable with a stable but unmaintained library. The package has low install friction, no dependencies, and a permissive BSD license. However, the lack of releases since 2018 and sparse documentation mean you should verify that its lazy patterns match your use case before committing to it.
Install
lazify on PyPI
pip
pip install lazifyuv
uv add lazifypoetry
poetry add lazifyInstalling Lazify
Before you install
Low install friction with no runtime dependencies. Repository is active with a recent commit in 2026, though the package itself has not been released since 2018.
License in practice
BSD license is permissive, allowing commercial and private use with minimal restrictions.
Quickstart
pip install lazify
from lazify import lazy
result = lazy(expensive_operation)
Verify before relying
- What lazy evaluation patterns or proxies the library actually provides beyond the Babel LazyProxy base.
- Whether the package is actively maintained or in maintenance-only mode despite recent repo activity.
- Python version compatibility, as requires_python is unspecified.
- Concrete API surface and available functions or decorators in the library.
