How do I check if github3 does not find resource?

for example:

import github3
g = github3.GitHub(token='mytoken')
i1 = g.issue('rmamba', 'sss3', 1) #exists, returns Issue
i2 = g.issue('rmamba', 'sss3', 1000) #does not exists, return NullObject

how do I do this:

if i is None:
  handle none

I can do if i2 is i2.Empty. But then with i1 it does not work because it returns valid issue and i1.Empty does not exist. I tried with NullObject but it always says it's false.

i1 is NullObject #false
i1 is NullObject('Issue') #false

so I had to do this for now:

if '%s' % i2 == '':
  handle None

because it works for both NullObjects and valid results returned

Sorry for the delay in getting back to you.

In your example you can very simply do

if i1:
    # Do things because it exists

if i2:
    # Do things because it exists

The NullObject is implemented to behave as a false-y value just like None, '', False, 0, [], {}, etc.

Empty which I suspect you do not have is meant for attributes. That said, both of these may be going away for 1.0: #670

Your input would be very welcome.
