Python

Python is central to countless development workflows, and Kloud Workspace ships with a finely‑tuned Python toolchain to keep you productive.

Key features provided out‑of‑the‑box:

• Python 3.11 runtime, ready for immediate use.
• Both pip and the lightning‑fast uv package manager.
• Opinionated linting & formatting with ruff its IDE extension.
• Language‑intelligence powered by Jedi (Pylance is unavailable in non‑official VS Code builds).
• Pre‑generated IPython (itself, not pre‑installed) profile that matches the Kloud Workspace color palette.

Package Management with uv

For day‑to‑day dependency work, we recommend uv, which offers:

• Near instant dependency resolution.
• Deterministic, lock‑file–friendly installs.
• Seamless compatibility with requirements.txt and pyproject.toml.

Linting & Formatting with ruff

Kloud Workspace bundles Ruff and its VSCode extension for real‑time feedback. Our default configuration is deep and opinionated:

• Custom caching and line formatting behavior.
• Auto-fixing capabilities enabled by default.
• Fine-tuned rules for indentation width and maximum line length.
• Targeting Python 3.11 for compatibility alignment.
• A carefully selected ruleset that includes and excludes specific error codes from multiple linting plugins.
• Context-aware formatting such as consistent line endings and formatting of docstring code.
• Special rules for import sorting and type-checking blocks.
• Per-file rule overrides to reduce noise in test directories.

Configuration Lookup

Kloud Workspace ships with a default Ruff configuration at ~/.config/ruff/ruff.toml that suits most projects. If you need custom linting rules, add a ruff.toml file at your project’s root.

You can also copy the default configuration with:

ws-cli config cp ruff

For more details, refer to the ws-cli documentation.

IDE Compatibility & Language Server

Kloud Workspace aims to provide the best Python development experience. However, due to licensing constraints, limitations exist in language server integrations.

Kloud Workspace is not an official Microsoft build of VSCode, and therefore, the proprietary Pylance extension and language server is not available.

Instead, Kloud Workspace ship the open-source Jedi Language Server, offering robust language server features such as:

• Blazing‑fast code completion.
• Go‑to‑definition & symbol search.
• Basic refactorings.

Optional Interactive Shell

For an enhanced REPL experience you can install IPython:

pip install ipython
# or: uv pip install ipython

Kloud Workspace already includes a custom IPython profile (/etc/ipython/ipython_config) whose prompt colors and syntax‑highlighting align with the Kloud Workspace's overall theme.

Once IPython is installed it will pick up these settings automatically—no additional configuration required.
