Python Language Attribute Access Basic Attribute Access using the Dot Notation


Let's take a sample class.

class Book:
    def __init__(self, title, author):
        self.title = title = author

book1 = Book(title="Right Ho, Jeeves", author="P.G. Wodehouse")

In Python you can access the attribute title of the class using the dot notation.

>>> book1.title 
'P.G. Wodehouse'

If an attribute doesn't exist, Python throws an error:

>>> book1.series
Traceback  (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Book' object has no attribute 'series'
