title: How come I can't "cd" to a folder in subprocess.call?
body: <p>I try to cd into a folder using subprocess.call(I want to run a command in that folder) the echo is to keep the power-shell window open.</p>
  
  <pre><code>subprocess.call([
              "C:\\WINDOWS\\system32\\WindowsPowerShell\\v1.0\\powershell.exe",  
              "cd C:\dev\git-sites\Babyshop",
              "echo 'test'"
          ])
  </code></pre>
  
  <p>When I try to run this I see a red error message flashing before the window closes.</p>
  
  <p>How can I keep the powershell open or get the output from it?
  How come it doesn't work?</p>
