How to get the host name of the current machine as defined in the Ansible hosts file

Question

I m setting up an Ansible playbook to set up a couple servers  There are a couple of tasks that I only want to run if the current host is my local dev host  named  local  in my hosts file  How can I do this  I can t find it anywhere in the documentation   I ve tried this when statement  but it fails because ansible hostname resolves to the host name generated when the machine is created  not the one you define in your hosts file   - name  Install this only for local dev machine   pip  name pyramid   when  ansible hostname     local
