+
+## Python Support
+
+The Function block supports Python as an alternative to JavaScript. Python code runs in a secure [E2B](https://e2b.dev) cloud sandbox.
+
+<div className="flex justify-center">
+  <Image
+    src="/static/blocks/function-python.png"
+    alt="Function block with Python selected"
+    width={400}
+    height={500}
+    className="my-6"
+  />
+</div>
+
+### Enabling Python
+
+Select **Python** from the language dropdown in the Function block. Python execution requires E2B to be enabled on your Sim instance.
+
+<Callout type="warn">
+If you don't see Python as an option in the language dropdown, E2B is not enabled. This only applies to self-hosted instances — E2B is enabled by default on sim.ai.
+</Callout>
+
+<Callout type="info">
+Python code always runs in the E2B sandbox, even for simple scripts without imports. This ensures a secure, isolated execution environment.
+</Callout>
+
+### Returning Results
+
+In Python, print your result as JSON to stdout. The Function block captures stdout and makes it available via `<function.result>`:
+
+```python title="example.py"
+import json
+
+data = {"status": "processed", "count": 42}
+print(json.dumps(data))
+```
+
+### Available Libraries
+
+The E2B sandbox includes the Python standard library (`json`, `re`, `datetime`, `math`, `os`, `collections`, etc.) and common packages like `matplotlib` for visualization. Charts generated with matplotlib are captured as images automatically.
+
+<Callout type="info">
+  The exact set of pre-installed packages depends on the E2B sandbox configuration. If a package you need isn't available, consider calling an external API from your code instead.
+</Callout>
+
+### Matplotlib Charts
+
+When your Python code generates matplotlib figures, they are automatically captured and returned as base64-encoded PNG images in the output:
+
+```python title="chart.py"
+import matplotlib.pyplot as plt
+import json
+
+data = json.loads('<api.data>')
+
+plt.figure(figsize=(10, 6))
+plt.bar(data["labels"], data["values"])
+plt.title("Monthly Revenue")
+plt.xlabel("Month")
+plt.ylabel("Revenue ($)")
+plt.savefig("chart.png")
+plt.show()
+```
+
+{/* TODO: Screenshot of Python code execution output in the logs panel */}
+
+### JavaScript vs. Python
+
+| | JavaScript | Python |
+|--|-----------|--------|
+| **Execution** | Local VM (fast) or E2B sandbox (with imports) | Always E2B sandbox |
+| **Returning results** | `return { ... }` | `print(json.dumps({ ... }))` |
+| **HTTP requests** | `fetch()` built-in | `requests` or `httpx` |
+| **Best for** | Quick transforms, JSON manipulation | Data science, charting, complex math |
