<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Thanks. I finally figured it out with the help of someone with a bit more Python knowledge than I have. I wasn’t able to figure out that the list was a list of arrays on my own. I would
try to get the type for each one of the items in the list (which was the list of tenants, ids, etc), but it would return that it was ‘<class 'keystoneclient.v2_0.tenants.Tenant'>’ and I didn’t know what to do with that since I expected something like <type
‘dict’> since that’s what it looked like when I just printed the line. After he pointed me to the fact it was an array (still not sure how to determine that other than just recognizing the output), I was able to pull the id just as you referenced.<o:p></o:p></span></p>

<p class="MsoNormal">When you make the API calls you're going to get back a list python objects which you need to iterate. I believe some APIs will let you ask for specific fields only, but this is simple enough:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal"> keystone = client.Client(username=Username, password=Password, tenant_name=Tenant,<o:p></o:p></p>

<div>
<p class="MsoNormal"> auth_url='http://%s:5000/v2.0' % (Ip))<o:p></o:p></p>
</div>
<div>
<div>
<p class="MsoNormal"> tenants = keystone.tenants.list()<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> tenant_ids = []<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> for tenant in tenants:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> tenant_ids.append(<a href="http://tenant.id">tenant.id</a>)<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Then you can process the tenant_ids list, of course once you done that you've lost the context of the object (like the name of the tenant).<o:p></o:p></p>

<p class="MsoNormal">For stuff like this the docs are your best bet along with introspecting the objects using the interactive python shell:<o:p></o:p></p>

(only) and push that send that to nova quota show and return just the CPU, memory, and storage metrics.</span><o:p></o:p></p>
