As Adriaan already pointed out: This is a scope problem.  In Aap
statements $var is using the stack of scopes, thus it works as you would
expect.  In Python commands this is not possible, thus you have to
explicitly specify that the scope stack has to be searched.  You can
prepend "_no", which stands for "no scope" (as if no scope was specified
in an Aap command).

Thus:

         @for d in expand2list(Subdirs):

Should be:

         @for d in expand2list(_no.Subdirs):
