<p>My question is how to exit out in Python main function? I have tried '<code>return</code>' but it gave the error <code>SyntaxError: 'return' outside function</code>. Can anyone help? Thanks.</p>

<pre><code>if __name__ == '__main__':
  try:
    if condition:
    (I want to exit here) 
    do something
  finally:
    do something
</code></pre>
