AInstallationandUseofPython Thisappendixaddresses1 afewissuesrelatedtotheinstallationanduseofPythonon differentplatforms. In addition, the accessing of Python in the cloud is commented inbrief. A.1 Recommendation: InstallAnacondaandOdespy If you install Anaconda, the only additional package you need for running all the software in the present book, is Odespy. The original version of Odespy was written in Python 2.7 by H.P. Langtangen and L. Wei (https://github.com/hplgit/odespy), but since the sad loss of Prof. Langtangen in October 2016, Thomas Anthony has made an updated version for Python 3.6 (https://github.com/thomasantony/odespy/tree/py36/odespy). In the present book, we use this version ofOdespy to demonstrate how ordinary differential equations alternativelymaybesolvedwith ready-madesoftware. A.2 RequiredSoftware Ifyou,forsomereason,decide to install somethingelse thanAnaconda,youshould know what software components that are required for running the programs in this book: • Python2 version3.6 [24] • NumericalPython3 (NumPy) [18,19] forarraycomputing 1 Some of the text is taken from the 4th edition of the book A Primer on Scientific Programming withPython, by H.P.
