argparse-addons
Additional argparse types and actions.
Decision gist · record as of 2026-08-14
Yes, if you need bounded integer validation in argparse and the feature set is sufficient—the package is stable, has no dependencies, and carries permissive licensing. No, if you require active maintenance or expect new features; the project is abandoned as of early 2023 and shows no recent activity.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6 or later.
- Low install friction with no runtime dependencies.
- However, the package is abandoned—last release was 2023-01-29 and no commits since then.

Alternatives
Verify before relying
pip install argparse_addons
import argparse
import argparse_addons
parser = argparse.ArgumentParser()
parser.add_argument('--port', type=argparse_addons.Integer(0, 255))
args = parser.parse_args(['--port', '47'])
print(args.port)- Whether the Integer type supports all edge cases (negative ranges, very large bounds) beyond the documented examples.
- Whether other custom types or actions beyond Integer are provided and documented.
- Whether the package works reliably with Python versions beyond 3.6 despite abandonment.
What it is and what it does
argparse_addons extends Python's built-in argparse module with additional type validators and action classes. The primary feature shown in the documentation is the Integer type, which validates command-line integer arguments against optional minimum and maximum bounds, producing clear error messages when values fall outside the specified range.
The package is a lightweight, dependency-free utility for developers building CLI tools who need stricter argument validation than argparse's basic int type provides. It requires Python 3.6 or later and integrates directly into standard argparse workflows by passing custom type objects to add_argument().
Use it for
- Validate bounded integers in CLI tools without writing custom validation logic.
- Enforce range constraints with automatic, user-friendly error messages when arguments fall outside bounds.
- Build command-line utilities that reject out-of-range numeric arguments at parse time rather than later in execution.
