None and null in python

1. to understand Python objects, first understand Python objects: python objects have three features: Identity, type, and value. Three features are assigned a value when an object is created. Only values can be changed. other values are read-only. The type itself is also an object. 2. Null and None are special types of Python. a Null object or NoneType has only one value, None. it does not support any operations or any built-in methods. if None is compared with any other data type, False is always returned. None has self... 1. Python object

To understand this, first understand the Python object:

Python objects have three features: Identity, type, and value.

Three features are assigned a value when an object is created. Only values can be changed. other values are read-only.

The type itself is also an object.

II. Null and None

Is a special Type of Python, Null object or None Type, it has only one value None.

It does not support any operations or any built-in methods.

If None is compared with any other data type, False is always returned.

None has its own data type NoneType.

You can copy None to any variable, but you cannot create other NoneType objects.



>>> Type (None)

>>> None = 0
False
>>> None =''
False
>>> None = None
True
>>> None = False
False
