title: add contact with telethon in python
body: <p>Recently I tried to add contact in telegram with telethon, according to this tutorial:
  1) <a href="https://stackoverflow.com/questions/44597384/add-new-contact-in-api-telegram-python-telethon">Add new contact in api telegram python telethon</a>
   ,I used this codes:</p>
  
  <pre><code>contact = InputPhoneContact(client_id=0, phone='+989122725691', first_name="user",
                          last_name="test")
  result = ImportContactsRequest(contacts=[contact])
  print(result)
  </code></pre>
  
  <p>But I in my output I get this :</p>
  
  <pre><code>ImportContactsRequest(contacts=[InputPhoneContact(client_id=0, phone='+989122725691', first_name='user', last_name='test')])
  </code></pre>
  
  <p>I can'd find out what is my problem, but when I go to my telegram app, this contact isn't add. </p>
