As we have seen, in Python, all variables have a type. And we can use the built-in dir
function to examine the capabilities of a variable. We can use type
and dir
with the classes that we create.
Code 14.7.1 (Python)
When this program executes, it produces the following output:
Type <class '__main__.PartyAnimal'>
Dir ['__class__', '__delattr__', ...
'__sizeof__', '__str__', '__subclasshook__',
'__weakref__', 'party', 'x']
Type <class 'int'>
Type <class 'method'>
You can see that using the class
keyword, we have created a new type. From the dir
output, you can see both the x
integer attribute and the party
method are available in the object.
