optionaldict
A dict-like object that ignore NoneType values for Python
Decision gist · record as of 2026-08-14
Yes, if you need a simple None-filtering dict for a new project and are comfortable with an unmaintained package. The code is straightforward enough that bugs are unlikely, but do not rely on it for critical systems or expect updates if incompatibilities emerge with future Python versions. For most use cases, a custom wrapper or a conditional dict comprehension is safer.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is frictionless—a pure-Python wheel with no runtime dependencies.
- However, the package has been abandoned since January 2021 (over 5 years without updates), so expect no bug fixes or compatibility work for newer Python versions.

Alternatives
Verify before relying
pip install optionaldict
from optionaldict import optionaldict
d = optionaldict(a=1, b=None)
d['c'] = 2
print(d) # None values are omitted- Whether None-filtering behavior applies to all dict operations (update, fromkeys, etc.) or only direct assignment
- Whether the package works reliably with Python 3.10+ despite no updates since 2021
- JSON serialization behavior when nested structures contain None values
What it is and what it does
optionaldict is a dict subclass that silently drops None values during assignment and storage, reducing boilerplate when building sparse data structures. It supports all standard dict operations and can be pickled or converted to JSON without special handling.
The package is minimal and dependency-free, making it trivial to install. However, it has not been maintained since January 2021, so there is no guarantee of compatibility with Python versions released after that date or any edge cases discovered in real-world use.
Use it for
- Building API request payloads where None fields should be omitted rather than sent as null
- Storing configuration objects where unset options should not appear in serialized output
- Reducing conditional logic when constructing dictionaries with optional fields
- Creating sparse data structures for caching or logging without explicit None filtering
- Serializing model objects to JSON while automatically excluding unset attributes
