Creating an object (instance)
Related code
class Dog:
"""Represents a dog."""
To make a real dog from our Dog class (called an instance or object),
we write the name of the class, followed by open and close parentheses:
... murki = Dog()
This creates a Dog instance and saves it in the variable murki.
... murki = Dog() print(murki)
<__main__.Dog object at 0x7f84b0fca5e0>
That's just Python telling us:
"This is a Dog object stored in memory with 0x7f84b0fca5e0 reference."
