No. The package is abandoned with no maintenance since 2019, license is unclear, and compatibility beyond Python 3.7 is unverified. For new projects, consider maintained alternatives. Only consider it for legacy codebases already locked to Python 2.7 or 3.7 where you control the environment.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Package classifiers list Python 2.7 and 3.7 support; compatibility with later versions is unverified due to abandonment.
- Installation is straightforward with low friction, but the package is abandoned—last release was 2019-11-23 and last commit 2022-05-14.
- No active maintenance means no fixes for compatibility issues.

What it is and what it does
BitMap is a Python class for storing and manipulating arrays of bits in a compact format. It provides basic bit operations—set, reset, flip, test—and bulk queries like count, any, all, and nonzero to find set bits. The class can also convert to and from string representations of bits.
The package depends only on future for Python 2/3 compatibility. It is abandoned as of 2019, with no recent maintenance or updates. The license is unclear, and compatibility with Python versions beyond 3.7 is unverified. Use only if you need a simple, self-contained bit array for legacy code or if you are willing to fork and maintain it yourself.
Use it for
- Implementing membership tests or bloom filters where you need a compact representation of which items have been seen.
- Storing boolean flags or feature flags in a space-efficient manner for large numbers of items.
- Educational purposes to understand bit-level operations and compact data structures.
- Legacy Python 2.7 or 3.7 projects that already depend on this package.
