title: When I Run my .py files, It gave me an invalid syntax error
body: <p>I use the python 2.7.12. My .py file contains the following:</p>
  
  <pre><code>Python 2.7.10 (default, Oct 23 2015, 19:19:21) 
  [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; print "hello"
  </code></pre>
  
  <p>When I try to run the file I get the following error:</p>
  
  <pre><code>  File "/private/tmp/fun.py", line 1
      Python 2.7.10 (default, Oct 23 2015, 19:19:21) 
               ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>I just use the <code>print "hello"</code>, so I don't think it's a code problem
  Who can tell me what's wrong?</p>
