There’s no variable null in Python; instead, there’s None keyword. It is a data type of the class NoneType
Python null variable
Example code. In Python, the ‘null’ object is the singleton
None. The None keyword is used to define a null variable or an object.
var = None if var is None: # Checking if the variable is None print("None") else: print("Not None")
Variable = None in Python? What does it mean?
It sets a variable named variable to None (Python’s version of a null/none type object).
See a demonstration example below:
variable = None print(type(variable))
Is it possible only to declare a variable without assigning any value in Python?
var = None
