error in activation-related try/except

[alexakarpov]

This is the block we have here in account/views.py:

    try:
        uid = force_text(urlsafe_base64_decode(uidb64))
        user = Customer.objects.get(pk=uid)
    except (TypeError, ValueError, OverflowError, user.DoesNotExist):
  

same block is present in pre-refactorin lectures, starting with Part 04, and up to including Part 10.

obviously, 'user', being a regular variable, doesn't have the DoesNotExist on it. If we replace the lower-case 'user' with, say, Customer (after we've created the class), the error goes away. Python being so dyamic and lenient is a double-edged sword )
