how to get first JSONs elements using python : <p>The public API respond me with JSON which has the next format</p>

<pre><code>{"ABCD-EFG":
    {"param1":"0.1234",
     "param2":"0.123456",
     "param3":"0.12334254"},
 "HIG-KLMN":
    {"param1":"0.3456",
     "param2":"0.05710" 
     "param3":"0.004903"
   ... } 
</code></pre>

<p>How can i get the List of the names (in this examle ABCD-EFG, HIG-KLMN) using Python3 ?</p>

<p>They can make changes in it every API get request sending</p>

<p>If it was like  'name' : 'ABCD-EFG', it would be easy. But it's not like that.</p>
