Python 3.13.0 : Script for python modules then installs them - updated with fix.

This script scans a folder full of .py files Python scripts, identifies all the external modules they import, filters out built-in ones, writes the installable ones to a requirements.txt file, and then installs them using pip—in parallel threads for speed.

I use the copilot and some comments are into my language, but I tested and works well:

NOTE: I updated with detection python modules based "from" and another issue: check if python module is instaled and step over that python module ...

This script will try to install many python modules, I can update to be better with these issues:

...some modules are default , some scripts are from another area, see Blender 3D with bpy python modules, some packages comes with same modules, this can be soleved with defined lists with unique items.

PyQt6 : Use python with ffmpeg tool ...

If you download a video from youtube with high resolution using a tool as yt-dlp then you can get two files with video and audio content:

... one with be with .f401.mp4 and another with .f251-9.webm and using the ffmpeg tool you can create one .mp4 file with both audio and video content.

News : Django Hijack

Log in and work on behalf of other users without having to know their credentials.

With Django Hijack, admins can impersonate and work on behalf of other users without having to know their credentials.

Comes with two versions available: v2.x and v3.x. The last v3.x provides a security first design, easy integration, customisation, out-of-the-box Django admin support and dark-mode. It is a complete rewrite and all former APIs are broken.

Python Qt6 : simple celtic knots tool with SVG file format.

Today, I try to create SVG file with an celtic knot design tool.

I used random values from -360 up to 360 for for Twist 1, Twist 2, and Twist 3 sliders.

The basic function is this, is created by artificial intelligence and not works very well.

        # Generate star polygon vertices
        points_cw = []
        points_ccw = []
        for i in range(steps):
            t = 2 * math.pi * i / steps
            r = outer_radius if i % 2 == 0 else inner_radius
            x_cw = center[0] + r * math.cos(t)
            y_cw = center[1] + r * math.sin(t)
            x_ccw = center[0] + r * math.cos(-t + math.pi / max(lobes, 1))
            y_ccw = center[1] + r * math.sin(-t + math.pi / max(lobes, 1))
            points_cw.append((x_cw, y_cw))
            points_ccw.append((x_ccw, y_ccw))

See one random example with this tool:

Python Qt6 : simple merge sprites images with unittest feature.

Python 3.13.5 : keras and torch and tensorflow on python version 3.13.5 !

I am not very satisfied with the security of the system in this area, I have noticed intrusions when I was at the Vodafone provider and now I am on mobile and they persist. I should improve my software and hardware protection and restart the system, but I have the impression that it won't help much considering the hacking capabilities that exist.

For now, I'm sticking with this solution, because it's quite good for simple tests with the Python language.

Today I will show you that the involvement of developers is somewhat lagging behind, and this can be seen from the analysis of the development progression across versions of the Python language, as it is not easy to implement in newer versions. Some packages, although important, are not available in newer versions.Today I will show you that the involvement of developers is somewhat lagging behind, and this can be seen from the analysis of the development progression across versions of the Python language, as it is not easy to implement in newer versions. Some packages, although important, are not available in newer versions. Let's see these python packages:

Keras is a deep learning API designed for human beings, not machines. Keras focuses on debugging speed, code elegance & conciseness, maintainability, and deployability. When you choose Keras, your codebase is smaller, more readable, easier to iterate on.

Python 3.13.5 : the groq tested with basic example !

About groq you can find on the official Grok website .

Today I tested the groq A.P.I. with the basic example :

import os

from groq import Groq

client = Groq(
    api_key="gsk_..."
)

chat_completion = client.chat.completions.create(
    messages=[
        {
            "role": "user",
            "content": "explain what groq is",
        }
    ],
    model="llama-3.3-70b-versatile",
)

print(chat_completion.choices[0].message.content)

The result of : "explain what groq is" is that :

Python Qt6 : ... simple resize image files.

I like the combination of Python development and the inclusion of the PyQt6 module. It is very fast and stable and allows me to create all sorts of tools to use.

Today I will show you another handy script that allows you to read all the image files from a folder and, depending on the selections: height, length, and/or aspect ratio, resize them and then place them in a folder created specifically for the resulting images.

Here is how the script looks, I clearly used artificial intelligence and it didn't take more than a few minutes, my evaluation, testing, and rearranging the interface took longer ...

Next, the install of the notebook python module

pip install notebook
Collecting notebook
...
Installing collected packages: notebook
Successfully installed notebook-7.4.4

This python package named voila will help us to use online graphic user interfaces:

pip install voila
Collecting voila
...
Successfully installed voila-0.5.8 websockets-15.0.1

The voila package need to work with ipywidgets python package:

pip install ipywidgets
Collecting ipywidgets
...
Successfully installed ipywidgets-8.1.7 jupyterlab_widgets-3.0.15 widgetsnbextension-4.0.14

Let's start the jupiter tool with this command:

jupyter notebook

I used an default python example with a slider:

import ipywidgets as widgets
from IPython.display import display

slider = widgets.IntSlider(value=5, min=0, max=10)
display(slider)

This command will start the web with the slider using the voila command:

voila test.ipynb

The result is this:

Python 3.13.5 : the manim python module - part 001.

I used this package few days ago and now I wrote about how can used it.

Update the new release of pip is available: 25.0.1 -> 25.1.1 , run this command:

python.exe -m pip install --upgrade pip

The documentation can be found on the official website.

python.exe -m manim render --help
Manim Community v0.19.0

Usage: python -m manim render ...

Let's use this source code:

from manim import *

class AdvancedAnimation(Scene):
    def construct(self):
        # Scene 1: Introduction
        title = Text("Advanced Animation with Manim").scale(0.76)
        self.play(FadeIn(title))
        self.wait(2)

        # Scene 2: Custom Animation
        circle = Circle().set_fill(color=BLUE, opacity=0.5)
        square = Square().set_fill(color=RED, opacity=0.5)
        self.add(circle, square)
        self.play(
            Rotate(circle, angle=TAU),

            run_time=2,
            rate_func=linear
        )
        self.wait()

        # Scene 3: Text Animation
        text = Text("This is a custom text animation", font_size=40).to_edge(UP)
        self.play(Write(text), run_time=2)
        self.wait()

        # Scene 4: Shapes Manipulation
        triangle = Triangle().shift(RIGHT * 2)
        self.play(GrowFromCenter(triangle), run_time=1.5)
        self.wait()

        # Scene 5: Transition to next scene
        self.play(Uncreate(triangle), FadeOut(text))

        # Scene 6: Final Animation
        final_text = Text("This is the end of our animation", font_size=50).to_edge(DOWN)
        self.play(FadeIn(final_text), run_time=1.5)
        self.wait(2)

# Run the animation

Python 3.13.5 : Get bookmarks from Edge browser with python.

Today I tested with these python modules json and pathlib.

This python script will get all bookmarks from Edge browser:

import json
from pathlib import Path

bookmark_path = Path.home() / "AppData/Local/Microsoft/Edge/User Data/Default/Bookmarks"

with open(bookmark_path, "r", encoding="utf-8") as f:
    data = json.load(f)

# Exemplu: listăm toate titlurile bookmark-urilor
def extract_bookmarks(bookmark_node):
    bookmarks = []
    if "children" in bookmark_node:
        for child in bookmark_node["children"]:
            bookmarks.extend(extract_bookmarks(child))
    elif bookmark_node.get("type") == "url":
        bookmarks.append((bookmark_node["name"], bookmark_node["url"]))
    return bookmarks

all_bookmarks = extract_bookmarks(data["roots"]["bookmark_bar"])
for name, url in all_bookmarks:
    print(f"{name}: {url}")

Python 3.13.5 : testing with flask, request and playwright python module.

Today some testing with these python modules: flask, request and playwright.

I used pip to install flask python package:

pip install flask

This will download a lot fo files and the will install the playwright tool.

First script is simple one will try to get cloudflare header on default ip:

from flask import Flask, request

app = Flask(__name__)

@app.route("/")
def detecteaza_ipuri():
    ip_client = request.headers.get('CF-Connecting-IP', 'Necunoscut')
    ip_cloudflare = request.remote_addr
    return (
        f"IP real vizitator: {ip_client}
"
        f"IP Cloudflare (vizibil de server): {ip_cloudflare}"
    )

if __name__ == "__main__":
    app.run(debug=True)

The next one will check more ...

from flask import Flask, request
import requests
import ipaddress

app = Flask(__name__)

def este_ip_cloudflare(ip):
    try:
        raspuns = requests.get("https://www.cloudflare.com/ips-v4")
        raspuns.raise_for_status()
        subneturi = raspuns.text.splitlines()

        for subnet in subneturi:
            if ipaddress.ip_address(ip) in ipaddress.ip_network(subnet):
                return True
        return False
    except Exception as e:
        return f"Eroare la verificarea IP-ului Cloudflare: {e}"

@app.route("/")
def detecteaza_ipuri():
    ip_client = request.headers.get('CF-Connecting-IP', 'Necunoscut')
    ip_cloudflare = request.remote_addr
    rezultat = este_ip_cloudflare(ip_cloudflare)

    return (
        f"IP real vizitator: {ip_client}
"
        f"IP Cloudflare (forwarder): {ip_cloudflare}
"
        f"Este IP-ul din rețeaua Cloudflare? {'DA' if rezultat == True else 'NU' if rezultat == False else rezultat}"
    )

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=5000)

Now, the script with the request python module:

import requests

url = "https://cobalt.tools"
headers = {
    "User-Agent": "Mozilla/5.0",  # Simulează un browser real
}

try:
    r = requests.get(url, headers=headers, timeout=10)
    content = r.text.lower()

    print(f"Cod răspuns HTTP: {r.status_code}")

    if "cloudflare" in content or "cf-ray" in content or "attention required" in content:
        print("Cloudflare a intermediat cererea sau a blocat-o cu o pagină specială.")
    else:
        print("Cererea a fost servită normal.")
except Exception as e:
    print(f"Eroare la conexiune: {e}")

The last one will use the playwright python module:

import sys
import re
from urllib.parse import urlparse
from pathlib import Path
from playwright.sync_api import sync_playwright

def converteste_url_in_nume_fisier(url):
    parsed = urlparse(url)
    host = parsed.netloc.replace('.', '_')
    path = parsed.path.strip('/').replace('/', '_')
    if not path:
        path = 'index'
    return f"{host}_{path}.txt"

if len(sys.argv) != 2:
    print("Utilizare: python script.py https://exemplu.com")
    sys.exit(1)

url = sys.argv[1]
fisier_output = converteste_url_in_nume_fisier(url)

with sync_playwright() as p:
    browser = p.chromium.launch(headless=True)
    pagina = browser.new_page()
    pagina.goto(url, wait_until='networkidle')
    continut = pagina.content()
    Path(fisier_output).write_text(continut, encoding='utf-8')
    browser.close()

print(f"Conținutul a fost salvat în: {fisier_output}")

This will create a file with the source code of web page.

Python 3.11.11 : Colab simple tests with Protocol Buffers - part 053.

The .proto file definition serves as a blueprint or schema for defining the structure of your data in Protocol Buffers. It plays a crucial role in ensuring data consistency and enabling efficient serialization and deserialization across different programming languages and systems.

You can find all steps on my colab_google - the GitHub repo.

News : Python-Fiddle online tool.

Python-Fiddle is an online Python playground where you can write, run, and share Python code directly from the browser without any need to install and maintain Python and packages on your computer. This platform was created make Python programming accessible to everyone and everywhere. We hope to make this a useful tool for learning, teaching, sharing, and collaborating on Python projects.

You can find this online tool on the official website.

Python : ... time-travel debugging project.

... ime-travel debugging, a technique that allows developers to "rewind" their code execution and inspect past states.

This is an old GitHub project from four years old.

• Execution Recording – The debugger logs each step of execution, including variable states and function calls.
• State Snapshots – It captures snapshots of memory at different points in execution.
• Reverse Execution – Developers can step backward through the code to analyze previous states.
• IDE Integration – Some tools integrate with VSCode and PyCharm for seamless debugging

This project is dependent on the following technologies:

• Node.js / Express
• Python 3
• SQLite
• better-sqlite3
• Nearley.js / Moo.js
• TypeScript
• HTML5 Canvas
• Webpack
• gcc / automake

Unfortunately, the Time Traveling Debugger project has only been tested on OSX and Linux, and Windows support is not officially available

Python 3.13.0 : bad management of python versions - need to fix into environment ...

I don't like how python management comes now, because some data god to \AppData\ and custom folder ... this will block some EXE because is not into environment ...

Will be more easy if the python team will make a management of all python on operating system area ... one reason is virtual environement , but this one python version of running ...

Can be better ? The management of python versions can be improved with simple user interface selection to manage all python versions and python modules, maybe a separate command shell more good thar python command on command shell, maybe a simple artificial intelligence just for user intercations and management of working ...

See this example , when I need to change to a lower version of python just to test some old python modules ...

Python Qt6 : simple animation with sprites.

Today I created with addon for Blender 3D and result is an image with sprites ...

I used that image with sprites and PyQt6 to animate my desktop screen, see the result:

This is the source code I used:

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

# diff PyQt6 versus old PyQt
from PyQt6.QtGui import QAction

from PyQt6.QtGui import QPixmap, QIcon
from PyQt6.QtCore import QTimer, Qt

class AnimatedWindow(QWidget):
    def __init__(self):
        super().__init__()

        # set window
        self.setWindowFlags(Qt.WindowType.FramelessWindowHint | Qt.WindowType.WindowStaysOnTopHint)
        self.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)

        # build layout 
        layout = QVBoxLayout()
        self.label = QLabel(self)
        layout.addWidget(self.label)
        self.setLayout(layout)

        # load sprite sheet from Camera_256px.png file name
        sprite_sheet = QPixmap("Camera_256px.png")  
        self.frame_width = sprite_sheet.width() // 11  # because I have 11 sprite on image
        self.sprites = [sprite_sheet.copy(i * self.frame_width, 0, self.frame_width, sprite_sheet.height()) for i in range(11)]
        self.current_frame = 0

        # 
        self.timer = QTimer()
        self.timer.timeout.connect(self.update_animation)
        self.timer.start(150)  # Schimbă frame-ul la fiecare 150 ms

        # 
        self.resize(self.frame_width, sprite_sheet.height())

        # left down on screen 
        screen = QApplication.primaryScreen().geometry()
        self.move(10, screen.height() - self.height() - 10)

    def update_animation(self):
        """Actualizează sprite-ul în QLabel"""
        self.label.setPixmap(self.sprites[self.current_frame])
        self.current_frame = (self.current_frame + 1) % len(self.sprites)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = AnimatedWindow()
    window.show()
    sys.exit(app.exec())

Python 3.11.11 : Colab simple image to video with stabilityai - part 052.

Today, a simple test with artificial intelligence and stabilityai/stable-video-diffusion-img2vid-xt.

The result is not very good, but I believe the source code can be improved ...

pipe = StableVideoDiffusionPipeline.from_pretrained(
    'stabilityai/stable-video-diffusion-img2vid-xt',
    torch_dtype=torch.float16,
    variant='fp16'
)

pipe.enable_model_cpu_offload()

You can find the source code on my colab GitHUb projects - catafest_069.

Python 3.13.3 : ... Nuitka package works with python 3.12 and MinGW.

Nuitka is licensed under the Apache License, Version 2.0; you may not use it except in compliance with the License.

Nuitka is the Python compiler. It is written in Python. It is a seamless replacement or extension to the Python interpreter and compiles every construct that Python 2 (2.6, 2.7) and Python 3 (3.4 - 3.13) have, when itself run with that Python version.

Nuitka translates the Python modules into a C level program that then uses libpython and static C files of its own to execute in the same way as CPython does.

I used the pip command:

python -m pip install -U nuitka
Collecting nuitka

This version of python : 3.13.0rc1 not work !!!

I need to upgrade my version to 3.13.3 version today after I open an issue on github repo!

python.exe -m pip install --upgrade pip

Same error, I uninstall the Python: 3.13.3 version and I install the python version 3.13.0 and use the pip again to install this python package.

python -m pip install -U nuitka

Using this version tell me same error with Windows and Visual Studio, but the MinGW is install from the first version.

The solution from artificial intelligence is to use another python version.

The test is a simple python script from the official website:

def talk(message):
    return "Talk " + message

def main():
    print(talk("Hello World"))

if __name__ == "__main__":
    main()

... and this python version works well with MinGW, the artificial intelligence used to fix these errors was ChatGPT.

Talk Hello World
