The first thing to know is there’s no null keyword in Python. Instead of null, there’s a None keyword used in Python. so there is no comparison between Python None vs null.
In other programming languages null is often defined to be 0, but in Python used None to define null objects and variables. But None is not defined to be 0 or any other value.
So, in Python, you should use
None it to represent the absence of a value, not
null. If you try to use
null in Python code, you will get a
null is not defined in the language.
Here’s an example of how to use
None in Python:
def print_name(name): if name is None: print("Name is not provided") else: print("Name is:", name) print_name("John") print_name(None)
As you can see,
None is used to represent the absence of a value for the
name parameter. If we call the function with
None, it will print the appropriate message.
Note: None and null difference and there is no null value in Python, you can use None like null.
