no, I think it can't,

I'm using yaml a few months ago, as I noticed, the last key
prevail.

import yaml


struct = yaml.load(file("yamlfile.yml" 'r'))



and struct will be a Python dictionary,



As I know, yaml modul is not part of standard Python library, but
most Linux systems has package, eg. Debian/Ubuntu has a
"python-yaml".
