title: os.execv without args argument
body: <p>I want to replace the current process with a new one using os.execv, this works fine unless you don't have any arguments.</p>
  
  <p>How can I call this even if I don't have an arguments to pass to the process I want to launch ?</p>
  
  <pre><code># Works fine, unless the arguments tuple wouldn't exist or be empty
  os.execv('process.exe', ('arg1', 'arg2'))
  </code></pre>
