pandas-linter 0.1.0

Static linter to optimize Pandas/Numpy code

pandas_lint

pandas_lint is a static code analysis tool designed to help you write more efficient and readable Pandas and NumPy code. It detects common anti-patterns and performance bottlenecks, offering suggestions to improve your data processing pipelines.

Features

• Performance Optimization: Identifies slow operations like apply(), usage of iterrows(), and inefficient string manipulations.
• Best Practices: Enforces standard Pandas coding styles and conventions.
• Safety: Warns about potential issues like SettingWithCopyWarning risks and modification of views.
• Easy Integration: Zero-config needed to get started, but fully configurable via pyproject.toml.

Installation

You can install pandas_lint directly from PyPI:

pip install pandas-linter
