What are the best practices for using class attributes in Python?

When using class attributes in Python, it's best to keep them immutable when possible, use them for constants, and avoid using them for instance-specific data.

Can you give me an example of a class attribute?

Sure! Here's a simple example:

class Circle:
    pi = 3.14  # class attribute
    
    def __init__(self, radius):
        self.radius = radius  # instance attribute

What’s the difference between class attributes and instance attributes?

Class attributes are shared across all instances of a class, while instance attributes are unique to each instance.

Are there any common mistakes to avoid with class attributes?

Yes, a common mistake is modifying a class attribute directly, which can lead to unexpected behavior in instances.
