+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+ and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+ overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+ advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+ address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+Email or PR.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.

+[](https://github.com/NodeX-AR/Pytml/commits/main)
+
+**Run Python in your browser with zero configuration — no server, just a script tag.**
+
+Pytml 2.5 is a lightweight JavaScript bridge built on **Pyodide 0.314.0.7**. Write Python inside HTML, interact with ordinary DOM elements, and use the small numbered UI syntax supported by the 2.5 runtime.
+
+---
+
+## Quick Start
+
+Add one line to your HTML:
+
+```html
+<script src="https://pytml.vercel.app/pytml.js"></script>
+```
+
+Then write Python:
+
+```html
+<py>
+print("Hello, world!")
+name = input("Your name? ")
+print(f"Hi {name}!")
+</py>
+```
+
+## Pytml 2.5 UI Syntax
+
+Inside a `<pyN>` block, Pytml 2.5 recognizes numbered UI tags such as:
+
+```html
+<py1>
+
+<btn1>1</btn1>
+<btn2>2</btn2>
+<txt1>
+
+def show(e):
+ print("You clicked a button")
+
+btn1.on("click", show)
+
+</py1>
+```
+
+`<btnN>` becomes a real `<button id="btnN">`, while `<inputN>` and `<txtN>` become real text inputs. Python indentation is preserved before the source is passed to Pyodide.
+
+## Normal HTML + Python
+
+Ordinary HTML IDs are available to Python:
+
+```html
+<button id="hello">Click me</button>
+<p id="result"></p>
+
+<py>
+def hello(event):
+ result.text = "Hello from Python!"
+
+hello.on("click", hello)
+</py>
+```
+
+## Packages
+
+Pytml keeps the Pyodide package workflow, including `micropip`:
+
+```python
+import micropip
+await micropip.install("numpy")
+
+import numpy as np
+print(np.mean([1, 2, 3]))
+```
+
+Packages available in the Pyodide environment can be used from Pytml, including common scientific packages such as NumPy, pandas and Matplotlib.
+
+## Multiple Programs
+
+`<py1>`, `<py2>`, `<py3>`, and so on are identifiers, not filenames. Blocks with the same identifier belong to the same program:
+
+```html
+<py1>
+x = 10
+</py1>
+
+<py1>
+print(x)
+</py1>
+
+<py2>
+print("Another program")
+</py2>
+```
+
+## Local Files
+
+Pytml supports local HTML files opened directly with `file://` when the Python code is inline:
+
+```html
+<script src="https://pytml.vercel.app/pytml.js"></script>
+
+<py>
+print("Hello from a local file!")
+</py>
+```
+
+No Python web server is required for this case. You can also use a local copy of `pytml.js` with `file://` by changing the script source to `./pytml.js`.
+
+A relative external Python file such as `<py src="app.py">` cannot be fetched from `file://` by normal browser JavaScript because of browser security restrictions; use inline Python or an HTTPS Python source URL for that case.
+
+See `local-file-test.html` for a ready-to-open example.
+

+# How to use Pytml?
+
+Pytml lets you run Python directly in HTML with one script tag.
+
+## 1. Start
+
+```html
+<script src="https://pytml.vercel.app/pytml.js"></script>
+```
+
+## 2. Write Python
+
+```html
+<py>
+print("Hello from Pytml!")
+</py>
+```
+
+## 3. Add HTML controls
+
+```html
+<button id="hello">Click me</button>
+<p id="output"></p>
+
+<py>
+def hello(event):
+ output.text = "Python handled the click."
+
+hello.on("click", hello)
+</py>
+```
+
+## 4. Use numbered Pytml controls
+
+```html
+<py1>
+
+<btn1>1</btn1>
+<btn2>2</btn2>
+
+number = ""
+
+def press(n):
+ global number
+ number += str(n)
+
+btn1.on("click", lambda e: press(1))
+btn2.on("click", lambda e: press(2))
+
+</py1>
+```
+
+## 5. Multiple programs
+
+`py1`, `py2`, and higher numbers are program identifiers. Repeating the same identifier shares that program's state.
+
+See `demo.html` and the `examples/` directory for runnable examples.
+
+
+### Local `file://` pages
+
+You can open an HTML file directly from your computer and still load Pytml from the public HTTPS URL:
+
+```html
+<script src="https://pytml.vercel.app/pytml.js"></script>
+```
+
+Inline `<py>` and `<pyN>` programs work in this mode. `local-file-test.html` is a ready-to-open example. A relative Python source file such as `<py src="app.py">` cannot be fetched from `file://` because browsers block normal JavaScript access to local files; use inline Python or an HTTPS source URL instead.

+ "@type": "Answer",

Heavy number crunching may be slower than server-side Python, but for demos, data viz, and scripting, it's perfectly fine."

+ </div>
+ <div class="space-y-4">
+ <div class="fade-up card">
+ <h3 class="text-sm font-bold">What is the actual bundle size of Pytml?</h3>
+ <p class="text-xs text-gray-400 mt-1">The Pytml wrapper itself is <strong>~15KB</strong> minified. The Pyodide runtime (~6MB) is loaded lazily from CDN only when you actually run Python code, so initial page load isn't blocked.</p>
+ </div>
+ <div class="fade-up card">
+ <h3 class="text-sm font-bold">Can I use Pytml with React, Vue, or other JS frameworks?</h3>
+ <p class="text-xs text-gray-400 mt-1">Yes. Pytml is framework-agnostic. You can drop the script tag in any HTML page, including those generated by React or Vue. It scans the DOM for <code><py></code> tags after the framework renders.</p>
+ </div>
+ <div class="fade-up card">
+ <h3 class="text-sm font-bold">What Python packages are supported?</h3>
+ <p class="text-xs text-gray-400 mt-1">Any pure-Python package available on Pyodide's repository – including NumPy, Pandas, Matplotlib, SciPy, and scikit-learn. C-extensions are not supported unless compiled to WebAssembly.</p>
+ </div>
+ <div class="fade-up card">
+ <h3 class="text-sm font-bold">How does Pytml handle errors and debugging?</h3>
+ <p class="text-xs text-gray-400 mt-1">Python tracebacks are captured and rendered directly in the browser terminal box. Syntax errors, runtime exceptions, and import errors all appear with line numbers and stack traces, just like a local Python REPL.</p>
+ </div>
+ <div class="fade-up card">
+ <h3 class="text-sm font-bold">Is there any server-side component or data sent to a backend?</h3>
+ <p class="text-xs text-gray-400 mt-1">No. Everything runs client-side in WebAssembly. No Python code, input, or output ever leaves your browser. This makes Pytml ideal for privacy-sensitive demos and educational tools.</p>
+ </div>
+ <div class="fade-up card">
+ <h3 class="text-sm font-bold">What are the performance limitations?</h3>
+ <p class="text-xs text-gray-400 mt-1">Pytml runs Python in a WebAssembly sandbox. It's roughly <strong>2-5x slower</strong> than native CPython for CPU-bound tasks, and memory is limited to the browser's tab allocation (usually 2-4GB). Heavy number crunching may be slower than server-side Python, but for demos, data viz, and scripting, it's perfectly fine.</p>

+# Summary
+
+Pytml is an open-source JavaScript library that enables developers to embed and execute Python code directly inside HTML web pages. It uses Pyodide—a port of CPython to WebAssembly—to run Python entirely in the browser without requiring a backend server (Pyodide, 2026).
+
+The library allows Python to be written directly in HTML using either `<py>` tags or `<script type="text/python">` elements. Pytml automatically handles Pyodide initialization, captures Python's standard output and input streams, and renders them in the browser's DOM, providing a seamless experience for developers (NodeX-AR, 2026).
+
+# Statement of Need
+
+Embedding Python in web pages traditionally requires manual loading of Pyodide, creating output containers, binding events, and converting data types—often requiring 10 or more lines of JavaScript boilerplate code for a simple "print hello" example. Pytml reduces this to a single HTML tag, making Python-in-the-browser accessible to educators, students, and developers who may not be familiar with WebAssembly or JavaScript toolchains.
+
+The library is particularly valuable for:
+- **Educational settings**: Teachers can embed interactive Python examples directly in course materials
+- **Prototyping**: Developers can quickly test Python code in a browser environment
+- **Interactive documentation**: Create web pages with live Python code execution
+
+# Use Cases
+
+## Educational Applications
+Pytml enables interactive coding exercises for Python education. Students can experiment with code examples directly in their browser without installing Python or configuring a development environment. This lowers the barrier to entry for learning programming.
+
+## Technical Documentation
+Technical writers and open-source maintainers can embed executable Python examples in documentation, allowing users to test code snippets immediately.
+
+## State of the field
+
+Several tools exist for running Python in web browsers. Pyodide provides CPython compiled to WebAssembly but requires JavaScript boilerplate for integration. Brython implements Python in JavaScript, offering similar functionality with different tradeoffs. Skulpt provides a lightweight Python-in-JavaScript implementation suitable for educational contexts. Pytml differs by providing a zero-boilerplate wrapper around Pyodide that handles DOM I/O automatically.
+
+## Software design
+
+Pytml is a JavaScript library that wraps Pyodide. On page load, it initializes Pyodide from a CDN, redirects Python's print() and input() to DOM elements, scans for `<py>` tags, and executes Python code in the browser. It transforms blocking input() calls into async JavaScript Promises.
+
+## Research impact
+
+Pytml enables educational Python use on any device with a browser, removing infrastructure barriers in resource-constrained environments. It supports rapid prototyping and interactive documentation.
+
+## AI usage disclosure
+
+GitHub Copilot was used as a coding assistant during the development of Pytml. The AI provided code comments and suggestions, particularly for boilerplate code and for official website. All code was reviewed, tested, and validated by the author before integration. No AI tools were used in the writing of this paper or its supporting documentation.
+
+## Rapid Prototyping
+Developers can quickly prototype Python-based web applications without setting up a backend server, making it ideal for early-stage development and testing.
+
+# Implementation
+
+Pytml consists of three primary components:
+
+1. **JavaScript Core**: Dynamically loads and initializes Pyodide (CPython compiled to WebAssembly) when the page loads. The core handles version management and ensures a single instance of Pyodide is shared across all Python blocks on the page (Drake, 2025).
+
+2. **Custom Parser**: Scans the HTML document for `<py>` tags and `<script type="text/python">` elements, extracting Python code for execution.
+
+3. **I/O Bridging Layer**: Intercepts Python's `sys.stdout` and `sys.stdin` streams and redirects them to DOM elements, enabling `print()` and `input()` to work natively in the browser.
+
+The library is distributed under the Apache License 2.0 and is available on GitHub (NodeX-AR, 2026). It has been released with persistent identifiers via Zenodo (10.5281/zenodo.20772922) and Software Heritage (swh:1:dir:f92a1f52bf3898ba006e009e4cbde4d9c40b9d73).
+
+# Limitations and Future Work
+
+While Pytml simplifies Python execution in the browser, it has some limitations:
+- **Large initial download**: Pyodide is approximately 6–7 MB, making Pytml unsuitable for lightweight pages
+- **Startup latency**: First execution can take several seconds while WebAssembly initializes
+- **Limited library support**: Only pure-Python packages are supported; C-extensions must be recompiled to WebAssembly
+
+Future development plans include:
+- Replacing Pyodide with a custom WebAssembly-compiled Python interpreter for faster loading
+- Support for scientific Python packages such as NumPy and Matplotlib
+- Enhanced debugging and error reporting capabilities
+
+# Acknowledgements
