26/10/15: --------- * CLASSES AND METHODS: ---------------------- * Possible conventions include capitalizing method names, prefixing data attribute names with a small unique string (perhaps just an underscore), or using verbs for methods and nouns for data attributes. *  It is not necessary that the function definition is textually enclosed in the class definition: assigning a function object to a local variable in the class is also ok # Function defined outside the class def f1(self, x, y):     return min(x, x+y) class C:     f = f1     def g(self):         return 'hello world'     h = g * Methods may call other methods by using method attributes of the self argument: class Bag:     def __init__(self):         self.data = []     def add(self, x):         self.data.append(x)     def addtwice(self, x):         self.add(x)         self.add(x) * The syntax for a derived class definition looks like this: class DerivedClassName(BaseClassName):     <statement-1>     .     .
