A Suggestion for Python Dictionary/Class

You might want to define all your instance variables in __init__() and
the overload __setattr__ to not allow anyone to set a value unless
already defined

class MyClass:
	def __init__(self):
		self.member = 0

	def __setattr__(self, name, value):
		if self.__dict__.has_key(name):
			self.__dict__[name]=value
		else:
			raise: "Error - no instance variable named "+ name

This will flag a runtime error if you try

o = MyClass()
o.menber = 1


Take care,
