Hi,  
I’m new to ansible and coming from a system where we have multiple CSV files defining  
projects, hosts, and users which I cannot easily change.

If I want to run certain commands I need to gather info from several files.

Is there is recommended way of doing this ?

I have been looking at the dynamic inventory, but I was hoping to us something better than  
passing environment variables to the inventory.

(Actually I’m a python guy and I was hoping that the inventory module could be written in python  
and actually called as a module internally by ansible rather than an executable script.)

Any direction or pointers would be appreciated,  
Con
