>>>import person
>>>tom = person.Manager('Parias lunkamba', 'mgr', 500000)
>>>Traceback (most recent call last):
  File "<pyshell#125>", line 1, in <module>
    tom = person.Manager('parias lunkamba', 'mgr', 500000)
AttributeError: module 'person' has no attribute 'Manager'

why the module in python 3.5 doesn't recognize the Manager class?
