title: "python" and "pip" command not found in Command Line
body: <p>I recently installed Python 3.6 for my Windows 10 (64bit) and I want to use pip, but before to install that, I need to execute the following command using the downloaded get-pip.py program:</p>
  
  <pre><code>python get-pip.py
  </code></pre>
  
  <p>Somehow this doesn't work and I get the following message from Command Line:</p>
  
  <pre><code>'python' is not recognized as an internal or external command, 
  operable program or batch file.
  </code></pre>
  
  <p>(I get the same message when I want to execute some pip commands)</p>
  
  <p>I tried a lot of "solutions" for installing pip, like downloading files from <a href="https://bitbucket.org/pygame/pygame/downloads/" rel="nofollow noreferrer">https://bitbucket.org/pygame/pygame/downloads/</a> but nothing happened, I got the messages...</p>
  
  <p>Could you explain to me why the Command Line doesn't know these commands and how can I install them?</p>
