BASIC IDEA
What you see here is the content of the attached PDF. The text is somehow a protocoll of an experiment to learn the programming language python from scratch. No pre-knowledge, no tools, no teachers! If you are in the same situation and you like to learn python since long, here you can enter and follow the steps.
STARTING WITH A REAL PROBLEM
Many years I opposed to learn python because in my view the language is really disgusting from the point of view of mathematics. But, one has to accept, that python has made its way in many areas including technology, science, and the arts. And because I needed urgently an acepptable software environment for all my theories and experiments there is sometimes the day of decision: you have to start or you can’t show many things.
There is another point: meanwhile I identified as main framework for our theories (which we are discussing on uffmm.org) the combination of ubuntu + ros (robot operating system) + tensoflow. Here python is the main langauge besides C/C++. Furthermore I detected many applications for our art projects, which are also strongly supported by python. Thus the motivation became stronger than my disgust about this quirky style of thinking.
In the attached PDF you can see how I battled through the python-jungle in 3 days producing a first outcome.
After these 3 days I would say, yes, python is a worthful tool to work with. I am convinced that we can solve most of our problems with it.
Therefore it is highly probable that you will find here more documents with python programs in the future. The idea is indeed to set up a local learning environment (LLE) which is small, flexible, portable, and very powerful. It should enable really intelligent machines to help people, not to substitute people. The future will belong to new men-machine couplings.
