OVERVIEW

The original plan was, to set up under ubuntu 14.04 a program-
ming environment which can use python3, spyder3 and as additional
software a speech-synthesis software like pyttsx. While everything
worked fine (see the first part of this article), it came to a ’show down’ when trying to combine python3 under ubuntu 14.04 with spyder3 and pyttsx3. All trials to overcome the problem led to new problems (see below). Finally I decided to give up the axiom of having ubuntu 14.04 on account of ros (robot operating system), because the primary tool is in this phase the programming language python. Python offers a ’universe of concepts’ on its own. And, who knows, there will be a day where ros will work with ubuntu 16.04 too :-). Then I installed ubuntu 16.04 (as upgrade from the internet) and checked the combination of python3, spyder3 and pyttsx3. It worked.

The pages 1-15 of the article describe a first update still using
ubuntu 14.04. Then it came to the crash when trying to combine python3 + spyder3 + pyttsx3. This led to the upgrade to ubuntu 16.04 and the new story. Before it came to the upgrade there was an important interaction with windows 10 helping to understand some limits and possibilities.

Abstract

After the description of how to use the python programming language under windows 10 starting from scratch in 6 posts we start here with some more posts dedicated to the question how to start programming
with python under linux using the distribution ubuntu 14.04. This distribution is selected because we will use later the ros (robotic operating system) as well as the tensorflow library.

Keywords: ubuntu 14.04, python 2, python 3, spyder

In the parts 1-4 it has been explored how it is possible to program under Windows 10  in python a small test project within an  actor-anvironment framework. It worked.

In part 5 it will be tested, whether and how one can transfer the sources from part 4 to the platform ubuntu 14.04.

After some searching of different options it revealed to be very straightforward: open a linux console and enter the command:

sudo apt-get install spyder3

This installs the same spyder version as for Windows 10 including python 3.4.3 with all the libraries, including numpy. The only thing one has to do manually is to download again the graphics.py module from John Zelle (you can find it with google-search for a direct download).
