How to Determine the Class Name of an Instance in Python?

Determining the Class Name of an Instance in Python

Identifying the class associated with an object instance can be essential for various programming tasks. Python provides several approaches to accomplish this.

Option 1: name Attribute

For new-style classes (the default in Python 3 ), the name attribute of the class can be accessed using the following syntax:

type(instance).__name__

This method is straightforward and returns a string representing the class name.

>>> import itertools
>>> x = itertools.count(0)
>>> type(x).__name__
'count'

Option 2: class__.__name Attribute

This method works for both new-style and old-style classes. It accesses the class attribute of the instance and then retrieves its name attribute.

instance.__class__.__name__

>>> x = int
>>> x.__class__.__name__
'int'

Conclusion

Both the name and class__.__name attributes provide reliable methods for retrieving the class name of an instance. The choice between them depends on the type of classes used in the code, with class__.__name providing compatibility for old-style classes in Python 2.
