How to create a new unknown or dynamic/expando object in Python

Question

In python how can we create a new object without having a predefined Class and later dynamically add properties to it ?

example:

dynamic_object = Dynami         


        

Answer 1

Use the collections.namedtuple() class factory to create a custom class for your return value:

from collections import namedtuple
return namedtuple('Expando', ('dynamic_property_a', 'dynamic_property_b'))('abc', 'abcdefg')

The returned value can be used both as a tuple and by attribute access:

print retval[0]                  # prints 'abc'
print retval.dynamic_property_b  # prints 'abcdefg'
