title: Read csv from Azure blob Storage and store in a DataFrame
body: <p>I'm trying to read multiple CSV files from blob storage using python.</p>
  <p>The code that I'm using is:</p>
  <pre><code>blob_service_client = BlobServiceClient.from_connection_string(connection_str)
  container_client = blob_service_client.get_container_client(container)
  blobs_list = container_client.list_blobs(folder_root)
  for blob in blobs_list:
      blob_client = blob_service_client.get_blob_client(container=container, blob=&quot;blob.name&quot;)
      stream = blob_client.download_blob().content_as_text()
  </code></pre>
  <p>I'm not sure what is the correct way to store the CSV files read in a pandas dataframe.</p>
  <p>I tried to use:</p>
  <pre><code>df = df.append(pd.read_csv(StringIO(stream)))
  </code></pre>
  <p>But this shows me an error.</p>
  <p>Any idea how can I to do this?</p>
