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.

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()

Blender 3D and python scripting - part 026.

Today I tested the bpy python module from Blender 3D software version 3.5 and I made this lite addon that showed me a modal dialog and checked and installed the Pillow python module.

Python tool oletools.

The recommended Python version to run oletools is the latest Python 3.x (3.9 for now). Python 2.7 is still supported for the moment, even if it reached end of life in 2020 (for projects still using Python 2/PyPy 2 such as ViperMonkey). It is highly recommended to switch to Python 3 if possible.

You can find it on this GitHub project.

See the all tools : mraptor, msodde, olebrowse, oledir, oleid, olemap, olemeta, oleobj, oletimes, olevba, pyxswf, rtfobj.

News : Python 3.12.0 release candidate 2 now available.

This new release comes with many improvements for developers.

Here are some of them.

Modules from the standard library are now potentially suggested as part of the error messages displayed by the interpreter ...

NameError: name 'sys' is not defined. Did you forget to import 'sys'?

• Many large and small performance improvements like - PEP 709;
• Support for the Linux perf profiler to report Python function names in traces;
• New type annotation syntax for generic classes - PEP 695;
• More flexible f-string parsing, allowing many things previously disallowed - PEP 701;
• Support for the buffer protocol in Python code - PEP 688;
• A new debugging/profiling API - PEP 669;
• Support for isolated sub interpreters with separate Global Interpreter Locks - PEP 684;

All PEPs can be found on this GitHub project.

Python 3.11.4 : Issues in Fedora with PyGobject and sway-tests

Today I wanted to test this repo named sway-tests.

I followed the steps there and received an error from gi.repository.

This error is related to another issue related to PyGobject.

In Fedora Linux distro, installing PyGobject is done with pip like this:

$ pip install PyGobject

In order to have no errors, the dnf or dnf5 tool should be used like this ...

I tested the functionality of this installation with a simple example:

import gi

gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

win = Gtk.Window()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()

It worked very well.

After solving this issue, I returned to the initial one and tested the sway-tests.

$ whereis sway
$ env/bin/pytest --sway=/usr/bin/sway
$ sudo env/bin/pytest --sway=/usr/bin/sway

I used the command both with and without sudo.

Both generated the same errors.

For the following command I had to install ... xorg-x11-server-Xephyr:

Xephyr is an X server which has been implemented as an ordinary X application. It runs in a window just like other X applications, but it is an X server ...

... the fixed centered black window specific to the xorg runtime appeared and somewhere on the side the terminal showed me a bunch of errors.

... obviously, I don't know how well sway-tests is implemented, now it's an archived repo, but I solved the use of PyGobject in python on the Fedora linux distribution.
