Well, I'm happy to change things but my python is only so good. And much of
that is based off of shell programming.
What the data looks like is fairly simple. I have a spreadsheet of host
information. Customer 'Alan' may have a dozen or so servers and customer
Ramit has another dozen or two. When I print these out they will be sorted
by customer but rolled into a single file.
The line "host_list[cust] = {}" creates the customer dictionary if that
customer doesn't exist. Then there's a host key with multiple layers:
host_list['alan']['webserver']['ip'] = '12.23.34.45'
host_list['alan']['webserver']['environ'] = 'Dev'
Make sense? As I do not know a lot about classes I'm not sure they are
better in this case than a multi-level dictionary. The data does not get
altered, just organized.
