title: How to make python program ".py" executable?
body: <p>I need to make a py program run on command just by name
  I can do that in by put the executable in /usr/bin/executable_program</p>
  
  <p>yes. I know I can make it by:</p>
  
  <pre><code>chmod +x file.py
  ./file.py
  </code></pre>
  
  <p>I just want when I write the program name "executable_program" in terminal it runs
  without the "./" and the ".py"</p>
  
  <p>Thank you...</p>
