Python isn't just for programmers
Small DIY project to open a gate through the Internet with the help of Python

Development Cluj Napoca, March 9, 2016, by Yeti
Estimated reading time:
When (learning) Python is concerned, there are more questions to be asked than how to turn that knowledge into a job?. Different forms of programming are becoming ubiquous in all kinds of work environments and the ability to code provides greater opportunities for non-programmers in their own projects or by adding values to the jobs they are already holding. This "new" world is more about understanding how things work at a conceptual level and less about writing a lot of code, and that's where programming languages as Python are great :)

There is a high probability that in software development a problem will occur several times, but with different inputs and outputs, to which the solution involves design patterns that come as generic means of treating these different expectations via an unique implementation ...

You don't care about performance
Profiling for performance

You don't care about performance, before you rant at me and include my mother in the conversation, answer some of these following questions:

  • Do you test for performance?
  • If you do, you do it in a automatic and repeatable manner?
  • Do you track, analyze and categorize the results? ...

Network simulations in Python using Networkx library
Networkx library will be used for some demonstrations about how much fun one could have with boring data structures like graphs

Development Cluj-Napoca, July 13, 2015, by Mihai
Estimated reading time:
It's important, if you want to get the best out of Networkx, to combine it with other tools from the scipy environment. And please do use the IPython Notebook (http://ipython.org/notebook.html) especially if you're planning a presentation. This way people attending it will at least easily see nice pictures of graphs and don't die of boredom while listening to your ranting...

About the author
I am a Web developer with a strong interest in history (all the data we have so far), military strategy, economics and philosophy (Kierkegaard). As development tools I use primarily Python with the Django framework (also used Flask+SQLAlchemy but didn’t like it). On the frontend I recently started using AngularJS and I like it so I’m working on improving my skills in this area. I’m also interested in scipy, numpy and networkx, while barely scratching the surface of what can be done with these wonderful tools.

Python objects
Understanding what classes are, when to use them, and how they can be useful

Development Cluj-Napoca, July 12, 2015, by Paul
Estimated reading time:
The class is a fundamental building block in Python. It is the underpinning for not only many popular programs and libraries, but the Python standard library as well. Understanding what classes are, when to use them, and how they can be useful is essential.
The class in Python is a mixture of the class mechanisms found in C++ and Modula-3, provide all the standard features of Object Oriented Programming. In a Python program all data is reprezented by objects or by relations between objects...
