title: 'py' works but not 'python' in command prompt for windows 10
body: <p>I installed Python on my computer.</p>
  <p>When I type <code>python</code> in the command prompt I get the following message:</p>
  <pre><code>'python' is not recognized as an internal or external command,
  operable program or batch file.
  </code></pre>
  <p>But when I type <code>py</code> it seems to be working and I get the following:</p>
  <pre><code>Python 3.7.0 (v3.7.0, Jun 27 2018, 04:59:51) [MSC v.1914 64
  bit (AMD64)] on win32 Type &quot;help&quot;, &quot;copyright&quot;, &quot;credits&quot; or &quot;license&quot;
  for more information.
  </code></pre>
  <p>Why is this happening?</p>
  <p>FYI: I checked the path variable in environmental variables and I don't see any path to python installation.</p>
  <p>But then how is visual code able to find the path to <code>python.exe</code> and able to run python code?</p>
  <p>I am confused.</p>
