Sample class with test harness too
this example from a Well House Consultants training course
Source code: animals.py Module: Y050
"""A Sample class called 'animal' is defined in this script; usually it will be loaded via an import or from, but it also includes a test harness / stand alone application for use if the file is called up directly. Although many languages use the word "this" or "self" as a keyword to represent the current object, in Python there is not a reserved word and although this or self if conventional it isn't vital that you use either of these words. In practise, we have used 'current' in some of the methods below, as we find that helps newcomers to understand what is going on In Python, the destructor method is called __del__ ; it's quite rare for a destructor to be needed, and it's unique in that you do not call the method yourself - rather, it is called for you when (or sometime after) you remove the last reference to the object.""" class animal: def __init__(current,name,age,factor,breed): current.called = name current.age = age current.f = factor current.type = breed def getname(current): return current.called + " Ellis" def birthday(current): current.age += 1 def geteage(self): return self.f * self.age def __del__(self): print "We need a vet" if __name__ == "__main__": hound = animal("Gypsy",2,7,"Lurcher") dawd = hound charlie = animal("Charlie",10,6,"moggy") hound.birthday() nyme = hound.getname() ayge = hound.geteage() print nyme,"is",ayge nyme = charlie.getname() ayge = charlie.geteage() hound = "" print nyme,"is",ayge print hound Learn about this subject
