title: Which abbreviations should we use for python variable names?
body: <p>In generally I'm using the standard naming stated in PEP-8 for variables. Like:</p>
  
  <pre><code>delete_projects
  connect_server
  </code></pre>
  
  <p>However sometimes I can't find any good name and the name just extend to a long one:</p>
  
  <pre><code>project_name_to_be_deleted 
  </code></pre>
  
  <p>I could use <code>pr_nm_del</code> , but this makes the code unreadable. I'm really suffering finding good variable names for functions. Whenever I begin to write a new function I just spent time to find a good variable name. </p>
  
  <p>Is there any standard for choosing certain abbreviations for well known variable names like, <code>delete,project,configuration, etc.</code> ? How do you choose short but good and readable variable names ? </p>
  
  <p>This question might be not depend directly to Python, but as different programming languages uses different variable names formatting I thought I limit this question to <em>Python only</em>.</p>
