What are the best practices for using super functions in programming?

Using super functions effectively can enhance code readability and maintainability. Here are some best practices: 1. Use super to call parent class methods when overriding. 2. Be mindful of the method resolution order (MRO). 3. Avoid excessive use of super in deep inheritance hierarchies.

Can you give an example of using super in Python?

Sure! Here's a simple example:

class Parent:
    def greet(self):
        return "Hello from Parent"

class Child(Parent):
    def greet(self):
        return super().greet() + " and Child"

child = Child()
print(child.greet())  # Output: Hello from Parent and Child

What should I avoid when using super functions?

Avoid using super in a way that creates confusion about which method is being called, especially in complex hierarchies. Also, don't rely on it for side effects, as it can lead to unexpected behavior.

Are there performance implications of using super?

Yes, using super can introduce a slight overhead due to the method resolution order lookup, but it's generally negligible compared to the benefits of maintainability and clarity.
