What is Python?NumericalMethods inMaterials Scienceand EngineeringMatthewGoodmanmgoodman@email.arMSE 350 - PythonAcedemic IntegrityPython is a general-purpose high-level programminglanguage. Its design philosophy emphasizes code readability.Python claims to “[combine] remarkable power with veryclear syntax”, and its standard library is large andcomprehensive. Its use of indentation as block delimiters isunusual among popular programming languages.[wik, ]Python OverviewWhy Python?HomeworkBibliography
