I have a reference to certain objects. What is the most pythonic way to

By "valid reference" you mean, you have initially:
obj = None

if obj:
This checks whether obj is considered True, not whether it is None.
e.g. obj=[] would not pass.
if None!=obs:
Would be OK, but the next one is better:
if obj is not None:
