deno_python

Python interpreter bindings for Deno.

Example

Import any locally installed Python package, for example, matplotlib:

import { python } from "https://deno.land/x/python@0.2.1/mod.ts";

const np = python.import("numpy");
const plt = python.import("matplotlib.pyplot");

const xpoints = np.array([1, 8]);
const ypoints = np.array([3, 10]);

plt.plot(xpoints, ypoints);
plt.show();

When running, you must specify --allow-ffi, --allow-env and --unstable flags. Alternatively, you may also just specify -A instead of specific permissions since enabling FFI effectively escapes the permissions sandbox.

deno run -A --unstable <file>

Python Installation

This module uses FFI to interface with the Python interpreter’s C API. So you must have an existing Python installation (with the shared library), which is something like python310.dll, etc.

Python installed from Microsoft Store does not work, as it does not contain shared library for interfacing with Python interpreter.

If the module fails to find Python, you can add the path to the Python in the DENO_PYTHON_PATH environment variable.

DENO_PYTHON_PATH if set, must point to full path including the file name of the Python dynamic library, which is like python310.dll (Windows), libpython310.dylib (macOS) and libpython310.so (Linux) depending on platform.
