title: Not able to run python from command prompt using 'python' command; it only takes 'py -3'
body: <p>I have installed Python 3.8.2 in my Windows 10 laptop</p>
  
  <p>When I run the command 'python' in the command prompt, it gives me a blank response and goes back to the command prompt.</p>
  
  <p>However when I run the command 'py -3' in the command prompt, python is launched.</p>
  
  <p>What can be the reason for this. Is there anyway I can launch python using the 'python' command in cmd?</p>
