If you are asking whether there is a null object is Python, the answer is: no, there isn’t. But it doesn’t mean you can’t assign a variable with no value.
The equivalent of null in Python is None. It does the same thing as null.
The case is very important here. You can’t write: none, NONE, nONE, etc., you have to write exactly None.
Here’s how it looks like inside Python:
a = None
print('There is a value assigned to the variable')
print('There is nothing assigned to the variable')
This code will return this output:
There is nothing assigned to the variable
The “if a” means the same as “if a is not None”. It’s just a quicker way to do it in Python.
You could also use “if a != None” but this code is not an elegant way, and you shouldn’t use comparison operators with None.
