Install

$ pip install durationpy

Parse

ns - nanoseconds
us - microseconds
ms - millisecond
s - second
m - minute
h - hour
d - day
w - week
mm - month
y - year

# parse
td = durationpy.from_str("4h3m2s1ms")

# format
durationpy.to_str(td)

Note: nanosecond precision is lost because datetime.timedelta uses microsecond resolution.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Converts between Python's datetime.timedelta objects and Go-style duration strings (e.g., "4h3m2s"), enabling easy parsing and formatting of human-readable time intervals.

Low friction: pure Python wheel with no runtime dependencies. Maintenance is aging—last commit 453 days old—but the repository remains active and the package has been stable since 2017.

MIT license permits commercial and private use with minimal restrictions; you must retain the license notice in distributions.

Usage

pip install durationpy

import durationpy
td = durationpy.from_str("4h3m2s1ms")
print(durationpy.to_str(td))

Nanosecond precision is lost because datetime.timedelta uses microsecond resolution.

Verdict: A lightweight, stable utility for Go↔Python duration interop with no dependencies and permissive licensing. Aging maintenance (453 days since last commit) is a minor concern for a stable, narrowly-scoped library with no known vulnerabilities.

Needs verification

Whether Python version support is truly unspecified or if there are practical constraints not documented in the package metadata.
