title: Python 3.7.0- where python3
body: <p>I have installed python 3.7.0 at my new laptop which runs with Windows.</p>
  
  <p>However, when I enter at the command prompt <code>where python3</code> then I get <code>INFO: Could not find files for the given pattern(s).</code></p>
  
  <p>But when I enter at the command prompt <code>where python</code> then I get <code>C:\Users\user\AppData\Local\Programs\Python\Python37\python.exe.</code></p>
  
  <p>I am quite confused because (if I remember right) when I had installed python 3.6.6 at my other laptop then essentially the opposite was happening; <code>where python3</code> was returning the latter message and <code>where python</code> was returning the former message and for me this makes more sense since I have installed in both cases a python 3 version.</p>
  
  <p>Why is this happening?
  What am I missing?</p>
  
  <p>Just to also mention that I run this python with PyCharm and everything works right so far as a python 3 version but I was just wondering about that.</p>
