tkinter : clean html source code with pydroid 3.

This script is an automated HTML cleaner designed to optimize web content for SEO, specifically tailored for HTML code generated by Blogger image uploads. By removing inline style attributes, CSS style blocks, and class parameters, it cleans clutter to improve the code-to-text ratio, enhancing page loading speed-a key ranking factor.
It strips anchor tags while preserving their internal content, eliminating unwanted external links or internal link equity leaks.
By keeping only structural tags like div and img, it produces lightweight, clean HTML markup that search engine crawlers can index and parse easily.

Let's see the source code:

tkinter : Acode.log Viewer and Clipboard Tool on Pydroid 3

This Python script creates a clean graphical user interface (GUI) using Tkinter, specifically designed to run inside Pydroid 3 on Android devices. Its main purpose is to automatically locate, open, and display the content of the Acode.log file generated by the popular Acode code editor app.
The program checks several common storage paths used by both the free and paid versions of Acode. Once the log file is found, the full content is loaded into a scrollable text area with horizontal and vertical scrollbars for easy reading of long log files. The complete file path, file size in KB, and total number of lines are shown clearly in the status bar at the bottom of the window.
Users can interact with the application through a simple File menu that includes three essential options: Reload (to refresh the log content), Copy All (to copy the entire log text to the system clipboard with one click), and Exit. Keyboard shortcuts (Ctrl+R, Ctrl+C, Ctrl+Q) are also supported for faster operation. The script handles missing files and read errors gracefully, displaying clear status messages and helpful guidance when the log cannot be located or accessed. It uses UTF-8 encoding with error replacement to ensure special characters do not break the display.
Ideal for Android developers and Acode users who need a fast, lightweight way to inspect application logs directly on their device without leaving the Pydroid 3 environment. The pure Tkinter interface requires no external libraries, making it fully compatible with Pydroid 3 out of the box.

Python : simple educational planisphere

This Python script functions as an educational planisphere designed for telescope observation. Instead of taking a live snapshot of the current sky (where most events would be hidden below the horizon during the day or off-season), it calculates and displays the expected positions of major astronomical events through late 2026—such as meteor shower radiants and NEO asteroid flybys—relative to Fălticeni, Romania (47.46^\circ\text{ N}, 26.30^\circ\text{ E}).
Oriented with North at the top, the code converts equatorial coordinates (Right Ascension and Declination) into local horizon coordinates (Azimuth and Altitude). It then projects these targets onto a 2D polar plot, indicating the cardinal direction (N, E, S, W) to point your telescope and labeling each event with its peak date and estimated rise time, before automatically exporting the chart as a high-resolution PNG image to your device's Download folder.

Python Qt : testing Browserless.io feature ...

The provided PyQt6 application is a desktop tool that allows a user to input any website address and instantly obtain a full‑page screenshot of that site using the Browserless.io cloud rendering service; the program begins by creating a simple graphical interface composed of a text field for entering a URL, a button that triggers the screenshot process, and a display area where the resulting image is shown, all arranged vertically for clarity and ease of use. When the user presses the button, the application reads the typed URL, constructs a request to the Browserless screenshot API using the user’s authentication token, and sends a JSON payload instructing Browserless to load the page and capture it in full, not just the visible viewport. Browserless processes the request by launching a headless Chromium instance, navigating to the specified website, rendering the page completely—including dynamic content—and returning a PNG image representing the entire scrollable webpage. The application receives this binary PNG data through an HTTP response, converts it into a QPixmap object, and displays it directly inside the PyQt window, effectively turning the GUI into a live screenshot viewer. This design allows developers to visually inspect websites without embedding a browser engine locally, relying instead on Browserless’s remote infrastructure to handle rendering, JavaScript execution, and screenshot generation. The code is intentionally minimal, focusing on clarity and functionality: it uses only standard PyQt widgets, avoids unnecessary complexity, and demonstrates how to integrate cloud‑based browser automation into a Python desktop application. The result is a lightweight tool that can preview websites, capture full‑page screenshots, and serve as a foundation for more advanced features such as zooming, saving images, asynchronous loading, or automated website testing workflows.
This script was created with copilot artificial intelligence, and tested by me.

Python Qt : simple tool to convert any source code to html area development.

Today. I will show this simple idea to convert any source code for html tag code with PyQt6.
The source code of this tool is not very big.I don't share because can be simple or you can customize as you want starting with any artificial intelligence and is more easy for you.
I used this on my blogger area, let's see the result for a simple example source code Google Apps Script from Gemini AI to html source code with div , pre and code html tags included in the result:

Python Qt : simple tool for audio dialogue in game development

Today, this script tool is a small desktop tool that lets you visually synchronize spoken audio with written dialogue. You load an audio file and the program generates a waveform so you can click or drag to select exact time ranges. At the same time, you select the matching text, and the tool creates timestamped dialogue segments.
Each segment includes a dialog ID, start time, end time, and the associated text. Segments appear in a list, can be played individually, deleted, or tested in a separate window where each dialog ID becomes a playback button. This makes it easy to verify timing and structure.
The entire project—audio path, full text, and all segments—can be saved or loaded as a JSON file. Older JSON formats containing only segments are automatically converted. The final JSON is ready for use in game engines like Godot or Unity for precise voice‑over playback.
I used artificial intelligence to fix some issues, this is the result:

Python 3.10.11 : python library-skills for your artificial intelligence.

The Python package library-skills is a lightweight command‑line toolkit designed to help developers build, test, and validate modular AI “skills.” These skills are small, self‑contained units of logic that can be executed independently or integrated into larger AI agents. The package focuses on simplicity, portability, and clear structure, making it useful for developers who want to experiment with tool‑calling systems or create custom capabilities for AI workflows.
A skill typically consists of a JSON descriptor and a Python function. The JSON file defines the skill’s name, description, and input schema, while the Python file contains the actual execution logic. This separation ensures that skills remain easy to document, validate, and reuse across different projects. With library-skills, developers can quickly inspect a skill’s schema, run it with custom input, or verify that its output matches the expected structure.
The command‑line interface provided by the package allows users to list installed skills, execute them directly, and validate input files without writing additional code. This makes the development cycle faster and more predictable. Instead of manually wiring functions together, developers can rely on a consistent interface that handles loading, parsing, and execution.
One of the main advantages of library-skills is its role in AI agent development. Modern agents often rely on tool‑calling, where the AI selects and triggers external functions based on user intent. Skills created with this package can be easily integrated into such agents, providing clear schemas and predictable behavior. This helps ensure that AI systems remain reliable, debuggable, and easy to extend.
Overall, library-skills is a practical utility for anyone building structured AI tools. It encourages clean design, modularity, and transparency, making it a valuable addition to Python environments focused on AI experimentation and agent development.
Let's install this python package.
python -m pip install library-skills

Now you can create skills for your artificial intelligence:
Create a folder with two files:
my_skill/
    skill.json
    skill.py
First file named skill.json:
{
    "name": "hello_skill",
    "description": "Returnează un mesaj simplu",
    "input_schema": {
        "type": "object",
        "properties": {
            "name": {"type": "string"}
        },
        "required": ["name"]
    }
}
The second file named skill.py
def run(input):
    name = input["name"]
    return {"message": f"Salut, {name}!"}
Run the skill into your folder:
library-skills run my_skill --input '{"name": "Catalin"}'
See the schema:
library-skills schema my_skill
Validate the input:
library-skills validate my_skill input.json
List the skills:
library-skills list
This is all you need for a default basic skill with the library-skills.

Python 3.10.11 : CVSS (Common Vulnerability Scoring System) with cvss python package.

This Python package contains CVSS v2, v3 and v4 computation utilities and interactive calculator (for v2 and v3 only) compatible with Python 3. CVSS (Common Vulnerability Scoring System) is an standardized method for rating the severity of security issues on a scale from 0 (no impact) to 10 (critical).
Let's install the cvss python package.
