make your own function that loops over the attributes, or spell it

Thank's, but this does not work for this case:
class A(object):
test = "test"
class B(object):
a = [A(),]
In [70]: reduce(getattr, "a[0].test".split("."), B)

<type 'exceptions.AttributeError'> Traceback (most recent call last)
/<ipython console> in <module>()
<type 'exceptions.AttributeError'>: type object 'B' has no attribute 'a[0]'
Seems that I have to use eval ?
I have a mapping text file (data) which contains such attributes strings
and those attributes should be read.
