TypeError: argument of type 'NoneType' is not iterable in python
<p>I am trying to get the VM size of a running process and using the following simple script. Here initially I am trying to get the reference of that process. But getting the error as --     </p>

<pre><code>if "DomainManager" in c:
TypeError: argument of type 'NoneType' is not iterable
</code></pre>

<hr>

<pre><code>import wmi

computer = wmi.WMI ()

for process in computer.Win32_Process ():

      c = process.CommandLine
      if "DomainManager" in c:
        print c
</code></pre>

<p>Would you please let me know the reason.</p>

<p>Thanks,
Rag</p>
