dep-prune

A tool to analyze your Python project's dependencies and identify unused imports.

1. Reads pyproject.toml - Supports multiple formats:

   • Poetry (tool.poetry.dependencies)
   • PEP 621 standard (project.dependencies)
   • PDM format
   • Handles dev dependencies and optional/group dependencies

2. Scans all Python files - Recursively finds all .py files in your project

   • Automatically excludes common directories (.git, __pycache__, venv, etc.)
   • Uses AST parsing for accurate import detection

3. Extracts imports - Finds all:

   • Regular imports: import package
   • From imports: from package import something
   • Handles nested modules correctly

Usage:

# Basic usage (analyze current directory)
uvx dep-prune

# Analyze specific directory
uvx dep-prune /path/to/project

# Specify custom pyproject.toml location
uvx dep-prune --pyproject /custom/path/pyproject.toml

# Verbose mode for detailed output
uvx dep-prune -v

Installation:

You'll need to install the toml package to run this tool:

pip install toml
