title: Find default pip index-url
body: <p>Is there a way to find which url(s) my pip command will look for when running something like <code>pip install &lt;package&gt;</code>?</p>
  
  <p>You can configure files like <code>.pip/pip.conf</code> and <code>.pypirc</code> to modify that default but I'd like to know if there is a way to know the mirror priority.</p>
  
  <p>Can I look for something specific running a command with the verbose flag (<code>-v</code>)?</p>
