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
Python 3.13.0a1 (tags/v3.13.0a1:ad056f0, Oct 13 2023, 09:51:17) [MSC v.1935 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

In the command line opened by python with >>>, I tested the old specific commands:

>>> help()

Welcome to Python 3.13's help utility!

If this is your first time using Python, you should definitely check out
the tutorial on the internet at https://docs.python.org/3.13/tutorial/.

Enter the name of any module, keyword, or topic to get help on writing
Python programs and using Python modules.  To quit this help utility and
return to the interpreter, just type "quit".

To get a list of available modules, keywords, symbols, or topics, type
"modules", "keywords", "symbols", or "topics".  Each module also comes
with a one-line summary of what it does; to list the modules whose name
or summary contain a given string such as "spam", type "modules spam".

help> modules

Please wait a moment while I gather a list of all available modules...

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 ...
