In programming, variables are used to store values of different types.
There is, however, a type that is special in that it is used to store nothing.
That value is called null.
In this post, we'll learn how to define a null variable in Python.
How to define a null variable
As mentioned before, null is a type used to mean nothing, or no value.
You can use this to define a variable without actually giving it a value.
Let's see how this is done in Python.
PYTHONvariable = None
print(variable)
BASHNone
This is useful for when you want to refer to a variable that has not been assigned a value yet, or to create a variable and then assign it a value later.
Conclusion
In this post, we learned how to define a variable in Python and assign it a null value.
Simply set the value of a variable to None
to define a null variable.
