introducing python statements now that you're familiar with python' core built-in object typesthis begins our exploration of its fundamental statement forms as in the previous partwe'll begin here with general introduction to statement syntaxand we'll follow up with more details about specific statements in the next few in simple termsstatements are the things you write to tell python what your programs should do ifas suggested in programs "do things with stuff,then statements are the way you specify what sort of things program does less informallypython is proceduralstatement-based languageby combining statementsyou specify procedure that python performs to satisfy program' goals the python conceptual hierarchy revisited another way to understand the role of statements is to revisit the concept hierarchy introduced in which talked about built-in objects and the expressions used to manipulate them this climbs the hierarchy to the next level of python program structure programs are composed of modules modules contain statements statements contain expressions expressions create and process objects at their baseprograms written in the python language are composed of statements and expressions expressions process objects and are embedded in statements statements code the larger logic of program' operation--they use and direct expressions to process the objects we studied in the preceding moreoverstatements are where objects spring into existence ( in expressions within assignment statements)and some statements create entirely new kinds of objects (functionsclassesand so onat the topstatements always exist in moduleswhich themselves are managed with statements
