How to go about referring to a null object in Python?

Question

Hi all, as per the title I want to refer to the null object in Python. How do I go about doing this?

All help appreciated!

Answer 1

In Python there is no concept of null, instead, Python uses None. None tests that two variables refer to the same object. 

See the example below:-

>>> foo is None 

True 

>>> foo = 'bar' 

>>> foo is None 

False
