Can't run python on powershell
<p>When I type python in PowerShell I get an error like:</p>

<pre><code>Program 'python' failed to execute: The system cannot find the file specified
At line:1 char:11
+ python.exe &lt;&lt;&lt;&lt; .
At line:1 char:1
+  &lt;&lt;&lt;&lt; python.exe
    + CategoryInfo          : ResourceUnavailable: (:) [], ApplicationFailedException
    + FullyQualifiedErrorId : NativeCommandFailed
</code></pre>

<p>I have added C:\Python27 and its sub directories to PATH. I can run it by typing python.exe. Can run scripts the same way.</p>

<p>I installed Python 2.7.11 64 bit.</p>
