Python 3.12.0 : Plyer example 001.

Plyer is a platform-independent api to use features commonly found on various platforms, notably mobile ones, in Python.

The project can be found on this GitHub project.

import time
from plyer import notification

if __name__ == "__main__":
	while True:
		notification.notify(title="Test",message="Text message",timeout=10)
		time.sleep(3000)

Let's see the most simple example with this python module.

Python 3.12.0 : PyAutoGUI example.

PyAutoGUI lets your Python scripts control the mouse and keyboard to automate interactions with other applications.

Make sure the modal dialog window is active and the desired text is visible before running the script.

This script waits for the user to activate the modal dialog window (for example, by clicking on the dialog window) and then moves the cursor to the coordinates of the label in the dialog window.

Copies the selected text to the clipboard using the classic Ctr and C keys.

Let's see the source code that does this.

import pyautogui
import time

# Display a short notification to prompt the user to activate the modal dialog window
print("Please activate the modal dialog window.")

# Wait for the user to activate the modal dialog window (you can click in the dialog window)
time.sleep(10) # Wait 10 seconds or enough time to activate the window

# Get the coordinates where you want to read the text on the label
x_label = 200 # Replace with the correct x coordinates
y_label = 300 # Replace with the correct y coordinates

# Move the mouse cursor to the coordinates of the label
pyautogui.moveTo(x_label, y_label)

# Select the text in the label using the mouse
pyautogui.dragTo(x_label + 200, y_label, duration=1) # Substitute the appropriate coordinates and duration

# Copies the selected text to the clipboard
pyautogui.hotkey("ctrl", "c")

# You can use the clipboard to access the read text
import clipboard
text_copied = clipboard.paste()

Python 3.11.0 : Exo - domain-specific programming language in python.

Exo is a domain-specific programming language that helps low-level performance engineers transform very simple programs that specify what they want to compute into very complex programs that do the same thing as the specification, only much, much faster.

You can find it on GitHub project and on the official webpage.

Let's install it with pip tool:

C:\PythonProjects>mkdir exo-lang_001

C:\PythonProjects>cd exo-lang_001

C:\PythonProjects\exo-lang_001>pip install exo-lang --user
Collecting exo-lang

Let's test with this default example but using virtual environments

This allow me to install Python packages in an isolated location from the rest of your system instead of installing them system-wide.

C:\PythonProjects\exo-lang_001>pip install virtualenv --user
...
C:\PythonProjects\exo-lang_001>python -m venv venv
C:\PythonProjects\exo-lang_001>venv\Scripts\activate.bat

Let's try a simple example from official webpage:

(venv) C:\PythonProjects\exo-lang_001>notepad example.py
# example.py
from __future__ import annotations
from exo import *

@proc
def example_sgemm(
    M: size,
    N: size,
    K: size,
    C: f32[M, N] @ DRAM,
    A: f32[M, K] @ DRAM,
    B: f32[K, N] @ DRAM,
):
    for i in seq(0, M):
        for j in seq(0, N):
            for k in seq(0, K):
                C[i, j] += A[i, k] * B[k, j]

Use this command and check the out folder:

(venv) C:\PythonProjects\exo-lang_001>cd out
(venv) C:\PythonProjects\exo-lang_001\out>dir 
...
 example.c   example.h

Python : Starting learn with futurecoder online tool.

This website with online tool can be a good start for test and learn python language programming.

They come with this intro:

This is a 100% free and interactive course for people to teach themselves programming in Python, especially complete beginners at programming. It is carefully designed to reduce frustration and guide the user while still ensuring that they learn how to solve problems. The goal is for as many people as possible to learn programming.

You can see in the next video tutorial how this works:

Simple install of python in Windows O.S.

Today I create this simple video tutorial for new python users.

In this video tutorial I show you how easy is to install the python programming language in Windows O.S.

After install you can use the command python and you can use the python shell to test this programming language.

Also, you can create a script file with any name.

for example name the file: test.py and run in the windows shell with: python test.py.

You can see this video tutorial on my youtube account.

Python Qt6 : Install and use python with Visual Studio.

Visual Studio is a very good tool for python programming language development.

Today I will show you how to use it with Visual Studio on a Windows operating system.

If you don't have Python install then start the Visual Studio installer and from all presents select the Python development workload.

Start Visual Studio and open a folder or open an empty file and save with the python language-specific extension: py.

Select the Python environment and add the new package with pip tool.

This is the python script I used to test:

import sys
from PyQt6.QtWidgets import QApplication, QWidget

def main():

    app = QApplication(sys.argv)

    w = QWidget()
    w.resize(250, 200)
    w.move(300, 300)

    w.setWindowTitle('Simple')
    w.show()

    sys.exit(app.exec())

if __name__ == '__main__':
    main()
