title: How should I use parse_mode='HTML' in telegram python bot?
body: <p>I'm trying to send a message in a channel with a bot, using Telegram API's <code>send_photo()</code> method. It takes a caption parameter (type <code>String</code>) but I can't format it through <code>parse_mode='HTML'</code> parameter...</p>
  
  <p>If I use something like this:</p>
  
  <pre><code>send_photo(chat_id, photo, caption="&lt;b&gt;Some text&lt;/b&gt;", parse_mode='HTML') 
  </code></pre>
  
  <p>it sends the message but without any kind of formatting. Does anybody know why? Thanks</p>
