Python Support

Python language support for OpenClaw agents. Provides environment setup, dependency management, linting, testing, and best practices for Python code execution. Use when running Python scripts, managing virtual environments, installing packages, debugging Python code, or ensuring code quality with linting and formatting.

Quick Start

Use this skill for all Python-related operations in OpenClaw.

Environment Check

Verify Python environment:

python3 --version
pip3 --list
which python3

Running Scripts

Always use absolute paths and specify Python interpreter explicitly:

python3 /path/to/script.py

Dependency Management

Install packages safely:

pip3 install --quiet package-name

For one-off scripts requiring dependencies, use inline installation with verification:

import subprocess
import sys

def ensure_package(package):
    try:
        __import__(package)
    except ImportError:
        subprocess.check_call([sys.executable, "-m", "pip", "install", "--quiet", package])

Best Practices

1. Shebang: Use #!/usr/bin/env python3 for executable scripts
2. Error handling: Always include try/except blocks for external operations
3. Encoding: Specify encoding="utf-8" for all file operations
4. Paths: Use pathlib.Path for cross-platform path handling
5. Output: Prefer JSON or machine-readable formats for structured output
