Python 3.10.12 : Simple example with SymPy - part 041.

SymPy is a Python library for symbolic mathematics. If you are new to SymPy, start with the introductory tutorial.

You can find a simple example with a partial differentiation on my GitHub colab repo.

Python 3.10.12 : My colab get images from imdb.com by the name - part 040.

Transformers provides thousands of pretrained models to perform tasks on different modalities such as text, vision, and audio.

Python 3.13.0a1 : How to use PyOTP for Microsoft Authenticator.

PyOTP is a Python library for generating and verifying one-time passwords. It can be used to implement two-factor (2FA) or multi-factor (MFA) authentication methods in web applications and in other systems that require users to log in.

Read more on this official webpage.

I teste with Microsoft Authenticator from Google play.

Install with pip tool and use this source code:

import pyotp

# Generare secret pentru utilizator
secret = pyotp.random_base32()

# Generare URL pentru codul QR
uri = pyotp.totp.TOTP(secret).provisioning_uri(name="UtilizatorExemplu", issuer_name="NumeServer")

# Exemplu de folosire a URI-ului într-o aplicație web sau pentru a genera un cod QR
print("Scanati urmatorul QR code in aplicatia Microsoft Authenticator:")
print(uri)

I run the python script:

python test_001.py
Scanati urmatorul QR code in aplicatia Microsoft Authenticator:
otpauth://totp/NumeServer:UtilizatorExemplu?secret=SPZICPQHAMWOIYCAZEHXZTPQDXEXZSWL&issuer=NumeServer

I used the uri output with one online tool to generate this QR image code and I tested with the aplication.

The account is added with NumeServer and UtilizatorExemplu.

Python 3.10.12 : My colab get images from imdb.com by the name - part 039.

You can use gspread and google-auth to get data from a spreadsheet from google drive and use it.

The colab notebook can be found on my colab repo on Github.

from google.colab import auth
auth.authenticate_user()

import gspread
from google.auth import default
creds, _ = default()

gc = gspread.authorize(creds)

# Open the spreadsheet by name
spreadsheet = gc.open('fiecare_saptamana')

# Choose a worksheet from the spreadsheet
worksheet = spreadsheet.get_worksheet(0)  # 0 represents the index of the first worksheet

# Get and print the data
data = worksheet.get_all_values()

#uncoment this line to print data sau add more source code to parse data
#print(data)

#the result will be 
#[['noreply@projects.blender.org', '437', 'notifications@github.com',  ...

PyScript - online tool .

PyScript is a platform for Python in the browser.

PyScript brings together two of the most vibrant technical ecosystems on the planet. If the web and Python had a baby, you'd get PyScript.

PyScript works because modern browsers support WebAssembly (abbreviated to WASM) - an instruction set for a virtual machine with an open specification and near native performance. PyScript takes versions of the Python interpreter compiled to WASM, and makes them easy to use inside the browser.

You can read more on the official webpage.

You can see my project tested with source code from a basic GitHub example.

Python 3.13.0a1 : Testing basic instalation.

Today I tested a prerelease version of Python which is version python-3.13.0a1-amd64, the maintenance status is prerelease, the first release was 2024-10-01, the end of support is 2029-10, and the release schedule is PEP 719.

I got this version of python from the official python page.

The checksum for the downloaded file is from the same page and I checked with the WinMD5Free tool.

WinMD5Free is a tiny and fast utility to compute MD5 hash value for files. It works with Microsoft Windows 98, 2000, XP, Vista, and Windows 7/8/10/11.

The installation is simple, theoretically you don't have to make changes, you can only select a custom folder.

Open a command line and type the python command to see the installed version.

python

I tried to use quit and exit to return to the interactive Python shell but these not work. I need to use Ctr +Z.

Just for testing, I installed some Python modules, my recommendation is to use a virtualenv for each project.

For update I used:

python.exe -m pip install --upgrade pip

Python 3.8.12 : Django with replit online tool - part 001.

Now with the replit online tool it is easy to test projects in Django. You must set a variable SECRET_KEY in settings.py and press the Run button. This will open the web page with your project.

In the command line area you can use python to generate this variable, see the source code:

~/Django001$ python
Python 3.8.12 (default, Aug 30 2021, 16:42:10) 
[GCC 10.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import secrets
>>> secrets.token_urlsafe(32)
'yIXPv6u4uCt4AUWlkU4NCuoyJiZlLx5IFm8kG6h8RtA'

This is result of these first steps:

Use this command to create a website named catafest001:

~/Django001$ python manage.py startapp catafest001

Add this website to settings.py from django_project:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'catafest001',
]

Use this command to create an user with a password:

~/Django001$ python manage.py createsuperuser
Username (leave blank to use 'runner'): 
Email address: catafest@yahoo.com
Password: 
Password (again): 
The password is too similar to the username.
Bypass password validation and create user anyway? [y/N]: y
Superuser created successfully.

You can see I let the username runner and the password I set to adminadmin.

Into web area I set the URL to /admin and I use the username and the password to login into admin area.

NOTE: Although I did the correct steps for a simple project in django with admin page, it won't let me login as admin ... maybe the replit online tool needs some other changes or the cause is different ...

Python 3.10.12 : My colab get images from imdb.com by the name - part 038.

You can find this notebook on my GitHub project.

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.

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()
