title: My Python shells and terminal in macOS don't allow me to ask the version type as 'python --version'?
body: <p>This is the resulting notice of entering "python --version"</p>
  
  <p>Traceback (most recent call last):   File "", line 1, in  NameError: name 'python' is not defined</p>
  
  <p>I have tried Python 2.7 and 3.6 shell as well as my terminal but cannot seem to figure out whats wrong.</p>
  
  <p>Eventually, I am trying to get pip.</p>
