# dict key tranformation table 
_ssh_to_ansible = {
    'user': 'ansible_ssh_user',
    'hostname': 'ansible_ssh_host',
    'identityfile': 'ansible_ssh_private_key_file',
    'port': 'ansible_ssh_port'
}

# host_config = config.lookup(box_name) # dict 
temp = {}
for k in _ssh_to_ansible:
    temp[_ssh_to_ansible[k]] = host_config[k]
  

@hostmaster that looks pretty minimal to me.

You could:

for host_key, ansible_key  in _ssh_to_ansible.items():
  temp[ansible_key] = host_config[host_key]

Other than that, no ideas.

@jtsoi Thanks.

Missing the context. Both of your solutions does the job. If you're after minimal code, there's also dict comprehension:

temp = {k: host_config[k] for k, v in _ssh_to_ansible.items()}

@vs-ab thank it is exactly what i am looking for
