You're making some rather dangerous and unwarranted assumptions here.
Consider your original code:

   def MyFunc ( varPassed ):
      print varPassed;
 
   MyFunc(nwVar)

What's going to happen if I do this:

   MyFunc( nwVar+1 )
   MyFunc( 27 )
   MyFunc( "abcde" )

If the thing passed in is a list or an object, you can modify the object in
place without trickery.  You can check that with the "type" operator:

   if type(varPassed) == list:
      pass
