Get the object name of a specific object from namedtuple

Question

I have recently discovered namedtuple and want to use it to replace my icky large class definitions but I am curious if there is a smart way to retrieve the object\

Answer 1

namedtuplescan be indexed, so you don't need to turn one into a dict or use vars() to do what you want:

MyStruct = namedtuple("MyStruct","Var1 Var2 Var3")
instance = MyStruct(1, 2, 3)

fields_to_print = {'Var1', 'Var2'}
print(', '.join('{}: {}'.format(field, instance[i])
        for i, field in enumerate(instance._fields)
            if field in fields_to_print))

Output:

Var1: 1, Var2: 2
