Python 3.13.16 : React frontend and python on Reflex Cloud.

Today, this simple test with artificial intelligence from reflex chat bot show how good and fast can be with one simple task.

Reflex compiles to a React frontend and a Starlette backend—the ASGI server that powers FastAPI. A familiar web stack, accessible to every Python developer. pandas, SQLAlchemy, scikit-learn, ...

After I ask to create a simple G.U.I. interface with all features from reflex, the chat bot result is this:

I built a one-page interactive playground that shows how a React-powered interface responds to Python state. Visitors can try five demos: a counter with event history, live preview controls, form validation, a searchable collection, and a dialog and toast.

Size: about 1,150 lines of Python across the page, four component modules, and four state modules. The integration section describes possibilities; it does not claim that external services are connected.

The interaction tests passed, and the page renders in the browser. I don’t have a reliable elapsed-time measurement for the build, so I can’t give an accurate creation time.

... the time of build was 4 minutes ...

Reflex comes with free features:

• Publish 1 app on Reflex Cloud
• Limited free usage for AI generation and hosting
• Refills periodically
• Public apps and public GitHub repos
• App code download and file editing
• Public sign-in with Reflex Auth
• Managed database

See the result online : this webpage.

tkinter : simple marshmallow demo.

About the marshmallow package

• It checks if your data has the correct fields.
• It verifies that each field has the right type.
• It helps you validate JSON before using it.
• It can convert Python data into clean JSON.

About your this source code:

• It loads the marshmallow package when the app starts.
• It reads the JSON you type in the input box.
• It tries to convert that text into Python data.
• It validates the data using your marshmallow schema.
• It shows the result or the error directly in the output box.
• It does not use print or message boxes.

Why this tool is useful

• You can test JSON visually.
• You can see validation errors instantly.
• You avoid console output.
• You keep everything inside the GUI.

Let's see the sourve code:

import json
import tkinter as tk
from tkinter import ttk

# ------------------ Package Load Test ------------------

try:
    from marshmallow import Schema, fields, ValidationError
    package_status = "Package marshmallow loaded successfully."
except Exception as e:

    full_name = fields.Str(required=True)
    city = fields.Str(required=True)
    birth_date = fields.Date(required=True)
    nicknames = fields.List(fields.Str(), required=True)


schema = PersonSchema()


# ------------------ Tkinter UI ------------------

    # Step 2: show raw JSON
    output.insert(tk.END, "RAW JSON RECEIVED:\n" + raw + "\n\n")

    # Step 3: JSON parsing
    try:
        data = json.loads(raw)
        output.insert(tk.END, "JSON PARSED OK.\n\n")
    except Exception as e:
        output.insert(tk.END, "JSON ERROR:\n" + str(e))

News : Real-Time Stock & ETF Analyzer in using tvscreener and Tkinter and pydroid3.

The tvscreener is a lightweight Python library designed to extract and analyze real-time financial data directly from TradingView's API without requiring paid API keys or complex authentication. It provides quick access to technical indicators, fundamental metrics, historical performance, and volume data for international stocks and ETFs. Explore the source code and documentation on the official tvscreener GitHub repository. The script provides a desktop interface (Tkinter GUI) powered by tvscreener logic to query market data on demand. This allow to choose a ticker symbol from the dropdown list (such as GOOGL, NVDA, AAPL, or ETFs like VUAA). Clicking Check triggers a background HTTP request without freezing the user interface, while displaying real-time progress via the progress bar. The script formats the API response into four core metric categories: Performance, Technical Indicators, Fundamentals, and Volume and Liquidity. Clicking Copy transfers the complete output directly to your system clipboard for quick sharing or note-taking.

tkinter : three algorithms for yahoo market with pydroid 3.

The script retrieves historical closing-price data for NVDA and VUAA.AS directly from Yahoo Finance.

First tab displays a candlestick chart for the selected time range. Two Simple Moving Averages are calculated automatically; their periods adapt to the chosen interval (for example SMA 5/10 on short ranges and SMA 50/200 on longer ones) and are shown in the legend. Clear dates appear on the horizontal axis.

Its second tab, ML Predictions, focuses on statistical modelling. The downloaded series is fitted with three algorithms: ordinary linear regression, polynomial regression (degree adjustable by the user), and a Random Forest regressor. All four lines—the original prices plus the three model outputs—are plotted on a single chart. Clear calendar dates appear on the horizontal axis, and an enlarged legend identifies each curve. Loading feedback is shown while data are fetched. The tab therefore converts raw Yahoo price history into immediate visual comparisons of linear, non-linear and ensemble trend estimates.

tkinter : python manager with pydroid 3.

The script is a lightweight package manager for Pydroid 3, built with Tkinter, designed to help you inspect, back up, and restore your Python environment on Android. It reads all installed packages using importlib.metadata, which works reliably in Pydroid 3, and displays them in a scrollable text area. A Check button scans the environment and lists every package with its version, while a Copy button places that list into the clipboard for quick sharing or documentation. The Save function opens a dialog and writes all detected packages into a Requirements.txt file, typically stored in the Download folder, allowing you to preserve the exact state of your environment. The Load function opens a file dialog, reads a requirements file, compares each entry with the currently installed packages, and installs only the missing or outdated ones using pip. Every operation updates a progress bar so you can see how many items have been processed. Overall, the script acts as a practical tool for backing up, restoring, and synchronizing Python packages on Pydroid 3, where traditional virtual environments and desktop-style package managers are not available.

tkinter : test colorchooser script on pydroid 3.

Learn how to use the Python Tkinter colorchooser module to create interactive graphical interfaces. This simple script opens a native color picker dialog and instantly updates your application interface based on user selection.

How the Python script functions:

The colorchooser module is imported to launch the native system palette window.

The askcolor function runs when triggered and waits for user input.

The script extracts the returned HEX color code from the selection.

The main window background and label text update immediately with the chosen color.

This lightweight code provides a simple way to add dynamic customization to desktop applications without installing external libraries.

Let's see the source code:

import tkinter as tk
from tkinter import colorchooser

def choose_color():
    # Opens the color picker dialog and returns a tuple: ((R, G, B), "#HEX")
    color = colorchooser.askcolor(title="Choose a Background Color")
    
    # Check if the user selected a color (didn't click Cancel)
    if color[1]: 
        hex_code = color[1]
        root.config(bg=hex_code)
        label_color.config(text=f"HEX Code: {hex_code}", bg=hex_code)

# Create the main window
root = tk.Tk()
root.title("Tkinter Colorchooser Example")
root.geometry("300x200")

# Button to trigger the color chooser dialog
btn_choose = tk.Button(root, text="Select Color", command=choose_color)
btn_choose.pack(pady=30)

# Label to display the chosen HEX code
label_color = tk.Label(root, text="No color selected", font=("Arial", 12))
label_color.pack(pady=10)

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:

tkinter : mini rss for NVDA

Today, I started new post with tkinter label. This is a demo real with pydroid3 android application to get data from rss and show me NVDA and more.

The tkinter package (“Tk interface”) is the standard Python interface to the Tcl/Tk GUI toolkit. Both Tk and tkinter are available on most Unix platforms, including macOS, as well as on Windows systems.

Python : djxi Django library .

djxi is a Django library that eliminates the HTMX scattering problem: it bundles URL patterns, view logic, and HTML template sections for a feature into a single DXEndpointBattery class, keeping all related code in one place.

See the official GitHub project.

Python : KivyMD on pydroid android I.D.E.

This Python script is a cross-platform mobile application built with KivyMD, a Material Design framework extension for Python's Kivy library. It combines a declarative user interface layout defined via Kivy Language (KV string) with Python event handling to create an interactive task management dashboard tailored for Android environments like Pydroid 3.

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.

Let's see source code:
