Question

I’m trying to get rid of exec in a code similar to this:

class A(object):
    for field in ['one', 'two', 'three']:
        exec '%s = "%s value"' % (field, field)

…so that:

>>> A.one
'one value'
>>> A.two
'two value'
>>> A.three
'three value'

EDIT: and also the requirement mentioned in the subject is met i.e. A.one is 'one value', before A is instantiated (not to be mistaken for A() instantiated).

Is there a way?

Answer 1

>>> values = 'one', 'two', 'three'
>>> A = type('A', (object,), {i: i + ' value' for i in values})
>>> A.one
'one value'
>>> A.three
'three value'
