There are also special attributes in it that begins with double underscores (__). So the __dict__ method is a very useful method in Python to display all attributes of an instance of a class or other data type such as a class itself. The pandas Dataframe class in Python has several attributes which include index, columns, dtypes, values, axes, ndim, size, empty and shape. For example, __doc__ gives us the docstring of that class. Luckily, we have some functions in Python available for this task.

A class creates a new local namespace where all its attributes are defined. For small data, it is easy to remember the names of the attributes but when working with huge data, it is difficult to memorize all the attributes.

Now you can see this attribute of the class displayed with the __dict__ method.
Almost everything in Python is an object, with its properties and methods. It is important to know the attributes we are working with. For example you might notice that __name__ might be missing from a class's dir() listing even though you can access it from the class itself. A Class is like an object constructor, or a "blueprint" for creating objects.
In Python, the class attribute is an attribute of the class which belongs to the class itself which means it is the attribute of the class rather than an attribute of an instance of a class. Attributes may be data or functions. We can even create instances of this class: f = Foo() This is a perfectly valid instance of Foo. The python examples provides insights about dataframe instances by accessing their attributes. OOP in Python3 Definition of attributes. Related Resources.
