Class Variable Inheritance

[Brian "bojo" Jones]

It became clear to me that mastervar inside of class a is a static 
variable, and is associated with all instances of classes that extend 
class a.  To get around this, I implemented a seperate mapping class:

class mapper:

	def __init__(self):
		self.mastermap = []

	def add(self, map):
		self.mastermap.append(map)

	def get(self):
		return self.mastermap

class a(object):

	def __init__(self):
		self.map = mapper()
		print 'called a'

class b(a):

	def __init__(self):
		self.map = mapper()
		print 'called b'
		self.mapvar()

	def mapvar(self):
		self.map.add('b')	

class c(b):

	def __init__(self):
		self.map = mapper()
		print 'called c'
		self.mapvar()

	def mapvar(self):
		super(c, self).mapvar()
		self.map.add('c')

if __name__ == '__main__':

	a1 = a()
	a2 = a()
	b1 = b()
	c1 = c()
	d1 = c() # Call C again

	print a1.map.get()
	print a1.map.get()
	print b1.map.get()
	print c1.map.get()
	print d1.map.get()
