infinity
All-in-one infinity value for Python. Can be compared to any object.
Decision gist · record as of 2026-08-14
No. The package is abandoned (last release 2020-06-03, no commits since) and high install friction makes it a poor choice for new projects. Modern Python versions have better alternatives: use float('inf') for numeric comparisons, or implement a custom comparable wrapper for your specific type. Only consider it if you have legacy code already depending on it.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- High install friction due to source distribution format.
- Package is abandoned—last release was 2020-06-03 with no maintenance activity since.
- Use only if you cannot migrate to a maintained alternative.

Alternatives
Verify before relying
pip install infinity
from infinity import inf
print(3 < inf) # True
print(inf + 5) # inf
print(float(inf) == float('inf')) # True- Whether the package works reliably with Python versions beyond 3.5, given its abandoned status and age
- Whether arithmetic behavior matches mathematical conventions in all edge cases
What it is and what it does
infinity provides a single Infinity class that represents an infinity value comparable to any object in Python, addressing limitations of the built-in float('inf'). Unlike float infinity, the Infinity class supports rich comparisons with arbitrary types (e.g., datetime objects) and enforces mathematically correct behavior—for instance, pow(1, inf) raises TypeError rather than returning 1.
The package supports arithmetic operations (addition, subtraction, multiplication, division, exponentiation) with sensible semantics: inf + 3 returns inf, 5 / inf returns 0, but undefined operations like inf - inf or pow(1, inf) raise TypeError. It also coerces to float, string, and boolean types. However, the package has been abandoned since 2020 with no active maintenance.
Use it for
- Implementing algorithms that need a universal upper or lower bound comparable to any type, not just numbers
- Creating priority queues or sorting logic where infinity must compare correctly with dates, strings, or custom objects
- Building mathematical or constraint-solving code that requires strict handling of undefined operations like inf - inf
- Replacing ad-hoc sentinel values (e.g., sys.maxsize) with a proper infinity abstraction
