import Tkinter does not work in Python 3
I am busy working through an older book called Tkinter GUI Application Development HOTSHOT by Bhashkar Chaudhary but the book is written for Python 2.7 I am using Python 3.10 and some of the statements in the book does not work for Python 3 so I will be posting the changes from time to time. The first issue I stumbled on is the import statement to import Tkinter. From the book you need to import it as:import Tkinter and this does not work in Python 3. in Python 3 use import tkinter (without the capital T) The test in IDLE as per the book will also fail for Python 3.The…

Good bye 2020 and good riddance
It’s safe to say we all had a 2020 to forget and unfortunately 2021 did not start out so well for me either. But hey, it’s a new year and new plans. Yes I finally decided to pivot my career to focus on Information Security thus I will still be posting about my programming here as well as my Information Security journey and anything I find interesting around these fields. I just finished an edX module in C programming. I’m still focusing on Python and plan to write the PCEP exam in a few weeks time if I have the budget. Today I started reviewing the PCEP course ware in…

Getting dirty with GUI development
Part of my degree studies are Python and then next semester includes GUI development using PyQt. So I thought why not get a head start as I’m wanting to build a few GUI applications for myself. I purchased Martin Fitzpatrick‘s “Create GUI Applications with Python & Qt5” eBook and videos and thus far having a lot of fun working through the book. The code is very well explained and the book is very easy to follow over all. Keep an eye for the review as soon as I’ve finished working through the book.

print(‘JetBrains Academy’)
I came across Jet Brains Academy this morning and started with their Python track. Thus far I am having a blast learning more about Python using their platform. They also feature a Java track that I will be looking at after completing the Python track. If you already use a JetBrains IDE like Pycharm then you are able to code the solutions to the questions from within your IDE. Other nice features I like are: Short byte sized lessons – pun intended Questions on the topics you just learned You can choose to start with the beginners project or jump ahead to intermediate or advanced projects if you are so…

Lock down learning
As most of us on planet earth are on lock down I thought that I’d have more time to learn more. For a start, Pluralsight has made all their courses available for free for the month of April and you do not need to provide credit card details when signing up. Personally I just finished Jessica McKellar‘s Intro to Python course on Oreilly which I really enjoyed. I’m looking forward to Jessica’s Intermediate course as she explains everything really well. I’m currently still studying for the RHCSA and doing Python courses on Pluralsight since it is free this month.

Day 1 of #100DaysOfCode
Today I started with the #100DaysOfCode challenge. The reason for starting the challenge is to force myself to code everyday and getting into the habit of coding. The 1st project I started is to access my CCTV RTSP stream from Linux, using a Python program, since the system only supports Windows and an Android App that feeds the video to a cloud service which I am not fond of. It took some time to figure out the correct RTSP URI format but I managed to get it working and using the RTSP library from PyPi I am now able to view a stream. You can find my GitHub repo here.…

Another blog post on Python
Just another heads up that I posted another blog post at ExchangeTimes.Net on how to make a specific Python version the default version on Linux. This is useful if you use one version of Python 90% + of the time and don’t want to specify which version of Python you want to run each time. You can find the post here.

Convert a PyQt ui file to a Python file on Linux
Part of my Python programming module at Unisa is based on creating GUI applications using the Qt framework, PyQt5 to be more precise. Unfortunately the study guide is based on Windows and not everything works the same way on Linux. The problem I had was not converting the .ui file as saved from Qt Designer to the .py file but with opening and running the application. The first conversion I did was straight from the guide as per below:
