title: lamda funtion in @bot.message_handler() not working properly in telebot python
body: <p>I tried to implement the following line of code in python script for a telegram bot building using telebot.</p>
  <pre><code>@bot.message_handler(func=lambda msg:True if msg.text.startswith('/test'))
  def test_start(message):
      msg=bot.send_message(message.chat.id,'This feature is under developement')
  </code></pre>
  <p>Above code gives me a syntax error.</p>
  <pre><code>@bot.message_handler(func=lambda msg:True if msg.text.startswith('/test') else False)
  def test_start(message):
      msg=bot.send_message(message.chat.id,'This feature is under developement')
  </code></pre>
  <p>This code solves the syntax error, but still, it doesn't do what I want it to do. When a user sends '/test some text' I want to identify this and do some actions after that.</p>
  <p>I am relatively new to python and this is my first time using telebot and lambda functions. So please help me in</p>
  <ol>
  <li>identifying why the 1st code gave me a syntax error.</li>
  <li>How to implement this startswith('/test') properly.
  Thank you so much in advance.</li>
