title: How to read all DICOM attributes/tags with pydicom?
body: <p>I'm trying to get a list of all the attributes (tags) of a given DICOM instance using pydicom.</p>
  <p>The list should include the attribute key/id, its <code>vr</code>, the value, and also the corresponding name.</p>
  <p>For example:</p>
  <pre><code>Tag: (2,0)
  VR: UL
  Name: File Meta Information Group Length
  Value: 246
  </code></pre>
  <p>I'd like to get some guidance on how to obtain this information since I can't find anything useful in the pydicom docs.</p>
  <p>My code is the following:</p>
  <pre class="lang-py prettyprint-override"><code>import pydicom
  from io import BytesIO
  
  dicom_data = await client.download_dicom_file(image_id)
  data = pydicom.dcmread(BytesIO(dicom_data))
  </code></pre>
