title: Telegram Bot "chat not found"
body: <p>I have the following code in Python to send a message to myself from a bot.</p>
  <pre><code>import requests
  
  token = '123456789:ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHI'
  method = 'sendMessage'
  myuserid = 1949275XX
  response = requests.post(
      url='https://api.telegram.org/bot{0}/{1}'.format(token, method),
      data={'chat_id': myuserid, 'text': 'hello friend'}
  ).json()
  print(response)
  </code></pre>
  <p>but this returns <code>{'description': 'Bad Request: chat not found', 'error_code': 400, 'ok': False}</code></p>
  <p>What am I doing wrong? I got <code>myuserid</code> by sending <code>/getid</code> to <code>@myidbot</code> and I got my token from <code>@BotFather</code></p>
