dictionary - How to convert Python dict to a specifically-typed object? -

using python 2.7 need convert dictionary typed object.

for illustration if have dict :

mapy = {'id': 1, 'name': 'bob'}

i need way generate class @ runtime given previous map , type name (which 'person' in example):

class person: def __init__(self): self.id = id self.name = name

should consider using meta-programming techniques , if 1 (decorators, metaclasses, ...)?

please note don't need convert dict object; need attach type info resulting object.

you can utilize next function generate __init__ method based on given dict:

def make_init(d):     def __init__(self, **kwargs):         name in d:             setattr(self, name, kwargs[name])      homecoming __init__

then, utilize 3-argument form of type create class @ run-time.

type_name = "person" person = type(type_name, (object,), { '__init__': make_init(mapy) })

finally, instantiate class using dictionary provide arguments __init__:

obj = person(**mapy)
