These notes are provided primarily for students at the University of Southampton (UK) in undergraduate, postgraduate and doctoral studies to help them install Python on their own computers should they wish to do so, and to support their learning of programming and computing, and subsequently their studies, in particular ...
Hans Fangohr, University of Southampton, UK, 2013
Spyder has developed into a fairly mature and very productive tool; here I try to provide a tutorial. This documentation is motivated by training courses in Python and computational modelling for students at the University of Southampton (see historical note for more detail ...
