handle empty response from http get call

I have a http get call in a self.method() which returns only [ ] in the response link in some cases. I want to use this output to handle exception in another method, like 

if type(self.method()) is 'NoneType':
   print "The object   is  not  present"
else:
    self.method2()

I am getting errors like

AttributeError: 'Response' object has no attribute 'URL'

How to catch the response output [] in if statement ?

Assuming that self.method() returns [] if the get failed:

response = self.method()
if not response:
    print 'response missing'
else:
    do_things(reponse)

this snippet uses the fact that an implicit bool() is cast on response which evaluates to False if the list is empty. it's basically a more readable version of: if response == []
