Re: [HTCondor-users] interpolation using the python bindings

[Jose Caballero <jcaballero.hep@xxxxxxxxx>]

Hi Tony

I already tried, and this is the best I got

>>> print classad.ExprTree("'$ENV(HOSTNAME)'").eval()
Undefined

which indeed doesn't really help too much.
Or is it resolved at submission time?
I guess it has to be, otherwise, not sure how it would work with
custom classads that depends on others like $(Cluster), which only get
a value after submission.

Thanks a lot.
Jose
