Klassikaal

Algemeen :

PLEASE NOTE: this training is developped als an introduction to Python. The focus is on understanding the code, coding excersices are limited to changing and extending of existing scripts.
If you want to learn to code in Python, we advise you to follow our 5-day training : Learn to program in Python

About this training
Car's, production lines, home automation, telephony, now a days there is little were computer programs are not essential. The basis of all this software is code - code in a certain programming lanquage. But how does this code work? In this training you wil learn what code is and what the base principles are. We will use the Python programming lanquage, mainly because of its power and versatility combined with it's simplicity.

Why Python?
Knowledge of the Python programming language is a pre in many roles (devops, data scientist, network engineer, etc.). Being able to program in Python is a much requested specialisation in more an more job openings and this will only become more in 2019. One of the reasons is that the language is relatively easy to learn and the programming lanquage is particularly useful for those who want to get into Artificial Intelligence, Big Data, Cyber Security projects and machine learning. All of these topics are topics that many companies are looking into becoming more specialised in.

What are you going to learn in this 3-day course?
In the course essential aspects of programming in general and of the programming lanquage Python in particular are covered. You will encounter many Python scripts in area's as diverse as home automation, configuration management, testing. With the knowledge gained you will be able to understand and (if necesarry) make small changes in those scripts.

If you already have some experience in programming in other lanqages, then our advise is to book our 3 day course THE PYTHON PROGRAMMING LANGUAGE.
