Use a "factory" function, and store a dictionary of instances as a class
property:
class myObj(object):
instances = {}
def __init__(self,a):
# the rest of your code
def makemyObj(a):
if a in myObj.instances:
return myObj.instances[a]
else:
new_instance = myObj(a)
myObj.instances[a] = new_instance
return new_instance
