In addition to the[Python Standard Library](https://docs.python.org/3/library/) and

the`pyscript` module, many 3rd-party OSS packages will work out-of-the-box with PyScript.

In order to use them you will need to delcare the dependencies using the`<py-env>` in the

HTML head. You can also link to`.whl` files directly on disk like in our[toga example](https://github.com/pyscript/pyscript/blob/main/pyscriptjs/examples/toga/freedom.html)

If your`.whl` is not a pure Python wheel then open a PR or issue with[pyodide](https://github.com/pyodide/pyodide) to get it added herehttps://github.com/pyodide/pyodide/tree/main/packages

If your`.whl` is not a pure Python wheel then open a PR or issue with[pyodide](https://github.com/pyodide/pyodide) to get it added herehttps://github.com/pyodide/pyodide/tree/main/packages. If there's enough popular demand the pyodide team will likely work on supporting your package, regardless things will likely move faster if you make the PR and consult with the team to get unblocked.

In order to use them you will need to declare the dependencies using the`<py-env>` in the

HTML head.

For example, NumPy and Matplotlib are available. Notice here we're using`<py-script output="plot">`

as a shortcut, which takes the expression on the last line of the script and runs`pyscript.write('plot', fig)`.

For examples see[the pyscript folder](pyscriptjs/README.md).

PyScript is a meta project that aims to combine multiple open technologies to create a framework for users to use Python (and other languages) to create sophisticated applications in the browser. It highlyintegrate with the way the DOM works in the browser and allows users to add logic, in Python, in a way thatfeel natural to web as well as Python developers.

<p>Message passing with linear algebra: a demo.</p>

<p>Imagine we have a chain graph that looks like this:</p>

<pre><code>O --> 1 --> 2 --> 3</code></pre>

<p>In NetworkX this graph would look like the following:</p>

G = nx.Graph()

nodes = list(range(4))

G.add_edges_from(zip(nodes[0:-1], nodes[1:]))

print(G.edges())

<p>This chain graph has the following adjacency matrix:</p>

adj_mat = np.eye(4, k=1)

print(f"A: {adj_mat}")

<p>And imagine that we have a message that lives on the graph:</p>

message = np.array([1.0, 0.0, 0.0, 0.0])

print(f"message: {message}")

<p>Try out message passing below by doing any one of the following steps:</p>

<pre><code>message @ adj_mat</code></pre>

<pre><code>message @ adj_mat @ adj_mat</code></pre>

<pre><code>message @ adj_mat @ adj_mat @ adj_mat</code></pre>
