What is the Null Object Equivalent in Python?

In Python, the Null object equivalent is the None object.

None is a built-in constant that represents the absence of a value or the null value in Python.

"An object frequently used to represent the absence of a value, as when default arguments are not passed to a function. Assignments to None are illegal and raise a SyntaxError. None is the sole instance of the NoneType type."

Reference: https://docs.python.org/3/library/constants.html#None

Example:

>>> none_variable = None
>>> print(type(none_variable)

<class 'NoneType'>

if none_variable is None:
    print(f"The variable {none_variable} is None")
