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.

Let's see the source code:

Python 3.14.x : SELinux basic script in Fedora Silverblue.

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.

    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 Qt : testing the SUA library using the pytrends and plotly.

People’s interactions can serve as a foundation for certain studies; here is a simple way to process data at low cost using Google Trends and lightweight Python packages such as SUA.

The script retrieves Google Trends search‑interest data for several Romanian economic keywords (such as munca, recesiune, somaj, inflatie, dobanzi) and I used copilot and gemini artificial intelligence. The copilot comes with bad result for fast asking simple scripts. It analyzes the data using the SUA library to estimate simple metrics like interest growth and volatility, then displays the results in a PyQt6 interactive chart where the X‑axis shows real calendar dates and the Y‑axis shows the Google Trends 0–100 normalized interest scale.

However, the script is limited by Google Trends constraints:

Google Trends allows maximum 5 keywords per request, so the script cannot query more terms at once.

Google Trends treats diacritic and non‑diacritic words as different searches (e.g., șomaj ≠ somaj), so the script uses non‑diacritic versions to avoid errors and improve compatibility.

Google Trends returns normalized values (0–100), not real search counts, meaning the data shows relative interest, not absolute volume.

The time series resolution is fixed by Google (weekly data for 12 months), so the X‑axis length depends on how many points Google provides.

These limitations come from Google Trends itself, not from the script.

If you got this error, then you need to limit the words, because Google returns a 400 Bad Request when your request is not valid for the internal Google Trends API.

    raise exceptions.ResponseError.from_response(response)
pytrends.exceptions.ResponseError: The request failed: Google returned a response with code 400

Let's run teh python script and output is this:

python main.py
Average interest growth (returns):
munca: 0.0072
recesiune: 0.3387
somaj: 0.0308
inflatie: 0.0660
dobanzi: 0.0157

Volatility (risk):
munca: 0.0256
recesiune: 2.9473
somaj: 0.1348
inflatie: 0.1607
dobanzi: 0.0527

The PyQt6 will create this bad result, what 1970 ?:

The issue in your script occurs because PyQt’s QDateTimeAxis expects the X‑axis timestamp to be expressed in milliseconds (since the Unix epoch), while Python’s .timestamp() function returns the value in seconds. When you send seconds instead of milliseconds, PyQt interprets a value that is 1000 times smaller, which places all chart points somewhere at the beginning of 1970 (right after January 1st, 1970).

Python 3.10.11 : testing zernio social platform with python.

Today, I get two free account on the zernio webpage.

This python script does three things:

First calls Zernio by sends GET https://zernio.com/api/v1/accounts using your Bearer token and loads the JSON response.

Then filters YouTube accounts: from the returned accounts[] list, it keeps only the items that look like YouTube (based on fields like platform/provider/network == "youtube").

Last one, prints and searches identifiers:

It prints the full JSON object for each connected YouTube account (first ~4000 characters), so you can see what fields Zernio returns.

It recursively scans that object for any string that matches a YouTube Channel ID pattern (strings starting with UC...) and prints the path and value for each match (e.g., meta.channelId = UCxxxx).

The result returns by printing to the console:

how many YouTube accounts Zernio returned.

the JSON for each YouTube account object.

a list of candidate channelId strings (and where they appear in the JSON).

Let's see the script:

import requests
import json
import re

ZERNIO_TOKEN = "sk_API_KEY"
API_BASE = "https://zernio.com/api/v1"

headers = {
    "Authorization": f"Bearer {ZERNIO_TOKEN}",
    "Accept": "application/json",
}

def is_youtube_account(acc: dict) -> bool:
    for k in ("platform", "provider", "network"):
        v = acc.get(k)
        if isinstance(v, str) and v.lower() == "youtube":
            return True
    return False

def find_uc_strings(obj, path=""):
    hits = []
    if isinstance(obj, dict):
        for k, v in obj.items():
            hits += find_uc_strings(v, f"{path}.{k}" if path else k)
    elif isinstance(obj, list):
        for i, v in enumerate(obj):
            hits += find_uc_strings(v, f"{path}[{i}]")
    elif isinstance(obj, str):
        # Typical YouTube channel id: starts with UC and is 24 chars, but we’ll be flexible
        if re.match(r"^UC[a-zA-Z0-9_-]{10,}$", obj):
            hits.append((path, obj))
    return hits

resp = requests.get(f"{API_BASE}/accounts", headers=headers, timeout=30)
resp.raise_for_status()
data = resp.json()

accounts = data.get("accounts", [])
yt = [a for a in accounts if is_youtube_account(a)]

print(f"Found {len(yt)} YouTube accounts in Zernio.\n")

for idx, acc in enumerate(yt):
    print(f"--- YouTube account #{idx} full object ---")
    print(json.dumps(acc, ensure_ascii=False, indent=2)[:4000])  # first 4000 chars
    print()

    hits = find_uc_strings(acc)
    print("Possible channelId candidates (paths):")
    for p, v in hits:
        print(f"  - {p} = {v}")
    print()

This is a part of result:

Python 3.10.11 : about the windows embeddable portable Python distributions fix pip.

Let's learn about the windows embeddable portable Python distributions.

• The Windows embeddable Python distribution is a minimal, self‑contained build of Python designed to run entirely from its own directory without installation.
• This distribution does not modify system settings, environment variables, or the Windows registry.
• Its structure makes it suitable for embedding Python inside applications or distributing Python as a portable runtime.

Typical use cases

• Bundling Python with standalone software that requires a predictable runtime environment.
• Running Python scripts in isolated environments where system‑wide installations must not be affected.
• Deploying portable utilities that must operate from removable storage or restricted systems.

When the embeddable distribution is not ideal

• General development workflows that rely on pip, external packages, or virtual environments.
• Educational or experimental setups where tutorials assume a standard Python installation.
• Projects that depend on automatic module discovery and dynamic package management.

The Role of python310._pth

• The file named python310._pth controls how the embeddable distribution locates and loads Python modules.
• When this file is present, Python enters an isolated mode in which only the paths explicitly listed inside the file are used.
• If the file does not include the line import site, the standard site initialization process is disabled, preventing access to site‑packages.

Typical structure of python310._pth

python310.zip
.
import site

Explanation of each entry

• python310.zip specifies the location of the standard library packaged as a zip archive.
• . allows Python to import modules from the root directory of the distribution.
• import site activates the site module, enabling automatic loading of Lib and site‑packages.

Enabling pip and external modules

• The embeddable distribution does not load external modules unless the appropriate paths are added to python310._pth.
• To enable pip and other installed packages, the file must include the Lib and Lib\site-packages directories.

Example of a Fully Enabled python310._pth

python310.zip
.
Lib
Lib\site-packages
import site

Testing the updated configuration

python -c "import sys; print(sys.path)"

Installing pip after enabling site‑packages

• Once the module paths are active, pip can be installed using standard methods.

python get-pip.py

python -m ensurepip

Verifying pip

python -m pip --version

Advantages of the embeddable distribution:

• Provides a predictable and isolated runtime environment.
• Does not interfere with system‑wide Python installations.
• Ideal for packaging Python with standalone applications.

Disadvantages of the embeddable distribution:

• pip and external modules are disabled by default.
• Requires manual configuration to behave like a standard installation.
• Not suitable for typical development workflows.

Clean, Ready‑to‑Use python310._pth File

python310.zip
.
Lib
Lib\site-packages
import site

This will fix the embeddable distribution, let's use this source code to fix the pip tool:

import os
import urllib.request
import zipfile
import shutil

PYTHON_DIR = r"C:\python-3_10_11"
SITE = fr"{PYTHON_DIR}\Lib\site-packages"

print("[INFO] Descarc pip.zip...")
urllib.request.urlretrieve(
    "https://github.com/pypa/pip/archive/refs/heads/main.zip",
    "pip.zip"
)

print("[INFO] Dezarhivez pip.zip...")
with zipfile.ZipFile("pip.zip", "r") as z:
    z.extractall("pip_src")

pip_src = "pip_src/pip-main/src/pip"

print("[INFO] Copiez pip în site-packages...")
target = os.path.join(SITE, "pip")
if os.path.exists(target):
    shutil.rmtree(target)

shutil.copytree(pip_src, target)

print("[INFO] Creez pip.dist-info minimal...")
dist = os.path.join(SITE, "pip.dist-info")
os.makedirs(dist, exist_ok=True)

with open(os.path.join(dist, "METADATA"), "w") as f:
    f.write("Name: pip\nVersion: 0\n")

print("[OK] pip instalat direct în Python.")
print("Rulează acum:")
print("   python -m pip --version")

Let's tun and test with PyQt6:

python fix_pip.py
[INFO] Descarc pip.zip...
[INFO] Dezarhivez pip.zip...
[INFO] Copiez pip în site-packages...
[INFO] Creez pip.dist-info minimal...
[OK] pip instalat direct în Python.
Rulează acum:
   python -m pip --version

python -m pip --version

Python 3.13.0 : another tool with PyQt6 to build an NPC database.

... another tool for game development, see more on my youtube channel.

Python 3.13.0 : mimesis python example.

Mimesis is a powerful data generator for Python that can produce a wide range of fake data in multiple languages. This tool is useful for populating testing databases, creating fake API endpoints, generating custom structures in JSON and XML files, and anonymizing production data, among other things. With Mimesis, developers can obtain realistic, randomized data easily to facilitate development and testing.

This python module can be install with pip tool easy.

See this simple example:

from mimesis import Person, Address, Text, Datetime
from mimesis.enums import Gender
def test_mimesis(locale: str, sex: str):
    person = Person(locale)
    address = Address(locale)
    text = Text(locale)
    dt = Datetime()
    gender = Gender.MALE if sex == "male" else Gender.FEMALE
    data = {
        "first_name": person.first_name(gender=gender),
        "last_name": person.last_name(),
        "full_name": person.full_name(gender=gender),
        "email": person.email(),
        "telephone": person.telephone(),
        "occupation": person.occupation(),
        "address": address.address().replace("\n", ", "),
        "city": address.city(),
        "postal_code": address.postal_code(),
        "country": address.country(),
        "birth_date": dt.date(start=1970, end=2005),
        "bio": text.text(quantity=2),
    }
    return data
if __name__ == "__main__":
    npc = test_mimesis("en", "female")
    for k, v in npc.items():
        print(f"{k}: {v}")

The result is:

News : Pythono and nuitka best optimization.

Nuitka is the optimizing Python compiler written in Python that creates executables that run without a separate installer. Data files can both be included or put alongside.

You can read more on the official website.

The install is easy with pip tool, then you can use this command.

python -m nuitka --help
Usage: python.exe -m nuitka [--mode=compilation_mode] [--run] [options] main_module.py

    Note: For general plugin help (they often have their own
    command line options too), consider the output of
    '--help-plugins'.

Options:
  --help                show this help message and exit
  --version             Show version information and important details for bug
                        reports, then exit. Defaults to off.

This python package need to have the Visual Studio Build Tools 2022 and need to use:

• Desktop development with C++
• MSVC v143 build tools
• Windows 10/11 SDK
• C++ CMake tools
• C++ ATL/MFC (optional but useful)

Let's install it.

I used this simple example:

import sys
from PyQt6.QtWidgets import QApplication, QLabel, QWidget, QVBoxLayout

def main():
    app = QApplication(sys.argv)

    window = QWidget()
    window.setWindowTitle("PyQt6 + Nuitka Demo")

    layout = QVBoxLayout()
    label = QLabel("Hello! This is a PyQt6 application compiled with Nuitka.")
    layout.addWidget(label)

    window.setLayout(layout)
    window.show()

    sys.exit(app.exec())

if __name__ == "__main__":
    main()

Use this command to see all plugins:

nuitka --plugin-list
