title: syntax error when using command line in python
body: <p>I am a beginner to python and am at the moment having trouble using the command line. I have a script test.py (which only contains <code>print("Hello.")</code>), and it is located in the map C:\Python27. In my system variables, I have specified python to be C:\Python27 (I have other versions of Python installed on my computer as well).</p>
  
  <p>I thought this should be enough to run <code>python test.py</code> in the command line, but when I do so I get this:</p>
  
  <pre><code>File "&lt;stdin&gt;", line 1
  python test.py
         ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>What is wrong? Thanks in advance!</p>
