title: comparing batch to python commands?
body: <p>Ok i have these commands used in batch and i wanted to know the commands in python that would have a similar affect, just to be clear i dont want to just use <strong>os.system("command here")</strong> for each of them. For example in batch if you wanted a list of commands you would type <strong>help</strong> but in python you would type <strong>help()</strong> and then <strong>modules</strong>... I am not trying to use batch in a python script, i just wanna know the similarities in both languages. Like in english you say " Hello" but in french you say "Bonjour" not mix the two languages. (heres the list of commands/functions id like to know:</p>
  
  <ol>
  <li>change the current directory</li>
  <li>clear the screen in the console </li>
  <li>change the prompt to something other than <strong>>>></strong></li>
  <li>how to make a loop function</li>
  <li>redirections/pipes</li>
  <li>start an exteral program (like notepad or paint) from within a script</li>
  <li>how to call or import another python script</li>
  <li>how to get help with a specific module without having to type <strong>help()</strong> </li>
  </ol>
  
  <p>@8: (in batch it would be <strong>command /?</strong>)</p>
  
  <p><strong>EDITED COMPLETELY</strong></p>
  
  <p>Thanks in Adnvance!</p>
