Here, se see that there are two *instance* attributes: `is_tool` and `tool_type`. The class `Tool` specifies that any `Tool` will have the value `True` for `is_tool` and `None` for `tool_type`, as this is the more general class.
There's also the `Tool` method `use_tool`, which, for a given instance, when executed will print `'Using tool.'`
As previously, we can initialize a `Tool` type object, storing it in `my_tool`. We can then access the attributes of `Tool` and carry out any `Tool` methods:
# access attribute
my_tool = Tool()
my_tool.is_tool
# use method
my_tool.use_tool()
However, what we're most interested in here is the concept of **inheritance**. In the code below, we see how you can inherit `Tool` properties within a new `class` object `Hammer`.
By passing `Tool` in when creating the `class` `Hammer`, `Hammer`-type objects will have the attributes and methods specifed within `Tool`.
We also see with the code here that we're specifying that `tool_type` for a `Hammer` will be `'Hammer'` and provide an additional instance attribute `why`, giving the `Hammer` a purpose - `'To hammer things.'`
class Hammer(Tool): #inherit Tool class
def __init__(self):
self.tool_type = 'Hammer'
self.why = 'To hammer things.'
We can now create a `Hammer`-type object and use the methods from `Tool` - such as `use_tool`- since that is inherited.
# Hammer has Tool attributes and methods
my_hammer = Hammer()
my_hammer.use_tool()
And, we can also access the `Hammer`-specific attributes:
# Hammer has Hammer attributes
my_hammer.why
However, you'll note that `Hammer` does *not* have access to the *attributes* from `Tool`:
# this code will error
my_hammer.is_tool
This is becuase our `Hammer` `class` defines its own *instance attributes*, overriding the instance attributes of the inherited class. We'll see in just a second how to avoid this using `super()`.
Further, note that inheritance is a one-way street. If you created a `Tool` class object (which is the parent class here) and does *not* inherit from `Hammer`, it only has access to `Tool` attributes and methods, so the following would execute without issue:
# Tool objects only have Tool attributes & methods
my_tool = Tool()
my_tool.is_tool
However, if you tried to access the `why` attribute on a `Tool` type object, you would encounter an `AttributeError`, as there is no attribute `why` in the `Tool` class object:
# Tool does NOT inherit from Hammer
# this code will produce an error
my_tool.why
Note in the example above that `tool_type` of `Hammer` class overrides the `tool_type` specified in the `Tool` class that it inherits. The `class` definition can and will override attributes and methods defined in the Parent class.
### `super()`
`super()` allows you to refer to the inherited, parent class, without naming it specifically.
This is particularly helpful when you want to extend the functionality of a class from which you are inheriting.
In the example above, we inherited from `Tool` in our `Hammer` definition and saw that while the `Tool` method were availalbe, the `Tool` instance attraibutes were *not*, due to the fact that our `Hammer` definition had overridden the `Tool` instance attribute definition.
So...how do we avoid that? This is where `super()` comes in. In the example below, we've added a single line of code (`super().__init__()`) to our `Hammer` definition from above. This specifies that we want to inherit the instance attributes from our parent class `Tool`.
class Hammer(Tool): #inherit Tool class
