flake8-no-chained-assignments 0.1.1

Flake8 plugin to prohibit chained assignments (e.g., a = b = c)

flake8-no-chained-assignments

A flake8 plugin that prohibits chained assignments.

Chained assignments (a = b = value) can obscure intent and lead to subtle bugs when mutable objects are involved. This plugin makes them a lint error, encouraging explicit, readable assignments instead.

Error codes

Code	Description
NCA001	Chained assignments are prohibited

Example

# Bad — triggers NCA001
a = b = 0
x = y = z = []

# Good
a = 0
b = 0

Installation

pip install flake8-no-chained-assignments

Or add it to your project's dev dependencies:

pip install -e ".[dev]"

Usage

Once installed, flake8 picks up the plugin automatically:

flake8 your_code.py

Example output:

your_code.py:3:1: NCA001 Chained assignments are prohibited

Configuration

You can ignore the rule per-line with the standard flake8 mechanism:

a = b = 0  # noqa: NCA001

Or disable it project-wide in setup.cfg / .flake8:

[flake8]
extend-ignore = NCA001

Development

git clone https://github.com/mrsndmn/flake8-no-model-forward-call
cd flake8-no-model-forward-call
pip install -e ".[dev]"
