This example demonstrates a lightweight, disposable SMTP server for local development, capturing outgoing email messages without actually transmitting them. It runs entirely on the command line using Python’s built-in `smtpd` module with the `DebuggingServer` class, which prints each received message to the console. The server listens on `localhost:25` (standard SMTP port) and requires superuser privileges, as indicated by the `sudo` prefix. The approach relies solely on Python’s standard library, making it a portable, zero-dependency tool for inspecting email payloads during testing or debugging, with no external frameworks or data sources involved.

Configuration of postfix for relay

This example shows the configuration of Postfix as a relay host, using three plain-text files. It displays the main configuration settings, SASL authentication credentials, and sender address canonical mappings. The visualization highlights key directives such as `relayhost`, `smtp_sasl_auth_enable`, and `sender_canonical_maps` directly from the gist. The renderer parses these files and presents their contents as structured code blocks, with no external libraries—only Python’s standard file handling and text processing.

Generic server listener for Blender

This example demonstrates a Blender add-on that runs a local HTTP server to receive 3D model import requests from an external source. It shows how Blender can act as a live listener, accepting OBJ or GLB file URLs via POST requests and queuing them for import. The code uses Python’s `http.server` and `socketserver` for the network layer, with a background thread processing a `queue.Queue` of incoming model URLs, while also tracking recent imports to prevent duplicates and exposing `/ping` and `/status` endpoints for monitoring.

This example demonstrates a minimal WebSocket server implemented in Python, showing how to establish a handshake and exchange framed messages. It uses `SocketServer.StreamRequestHandler` for the network layer, manually performs the WebSocket handshake via `sha1` and `b64encode` against the defined magic string, and parses incoming frames by XOR-masking payload bytes. The code handles payload lengths up to 64-bit values and sends text frames with a 129 opcode. It prints received messages to the console, illustrating the core protocol mechanics without any visualization or data rendering.

Serve static file with golang

This example demonstrates a minimal Go web server that serves static files from a local directory. It uses the `net/http` package’s `FileServer` handler to map the root URL path to the folder `D:/dev/static`, while `http.ListenAndServe` binds the server to port 5555. The code also logs a startup message via the `log` package. No dynamic data processing or client-side visualization is involved; the server simply delivers any requested file (HTML, images, etc.) over HTTP.

This example demonstrates a secure HTTP POST request that sends a small JSON payload containing a message, an ID, and a timestamp to a local server endpoint. The Python script builds the request using the `requests` library, formats the data with `json.dumps` (using compact separators and sorted keys), and includes custom authentication headers (`x-pk` and `x-pass`). The server responds with an encrypted string, which the script prints alongside the original data and formatted payload for verification.

Práctica: Crear un Webserver Flask en el Celular con Tailscale (VPN Red Privada), para OpenWeatherMap

This example demonstrates a practical workflow for hosting a Flask web server on a mobile phone and making it accessible over a private network using Tailscale. The server fetches current weather data for Tijuana from the OpenWeatherMap API using the `requests` library and renders it as a simple HTML page. The code configures Flask to listen on all interfaces (`host="0.0.0.0"`), then relies on the Tailscale VPN to route traffic securely between the phone and a laptop or PC. The presentation focuses on the setup process, including installing Python and Flask on an iPhone via iSH Shell, rather than displaying a particular visualization technique.

This example demonstrates a minimal "Hello World" visualization using the Python library, rendering text output to the console. The script, defined in `demo.py`, calls the built-in `print()` function to output the string "hello world". It serves as a basic template for testing execution environments and showcasing the simplest possible code structure, with no external data sources or graphical rendering involved.

Python debugging an exception

This example shows a minimal Python script that demonstrates how to catch and format an exception. It deliberately triggers an exception by assigning `1` to `temp` after initially setting it to `None`, then uses `sys.exc_info()` to retrieve the exception type, value, and traceback. The code prints both the string and representation of the exception, and finally formats the full traceback with `traceback.format_exception()`. The output displays the error message and stack trace in the console, illustrating the standard workflow for handling and reporting exceptions in Python.
