A developer is writing a utility class 'StringUtils' with a method 'is_palindrome' that checks if a string is a palindrome. The method does not need any instance or class data. Which method definition is appropriate?

@classmethod def is_palindrome(cls, s): return s == s[::-1]

def is_palindrome(self, s): return s == s[::-1]

@staticmethod def is_palindrome(s): return s == s[::-1]

def is_palindrome(s): return s == s[::-1]

A developer is building a web framework. They need to apply multiple decorators to a single view function: one to check authentication and another to log requests. The decorators must run in a specific order: authentication first, then logging. Which stacking order achieves this?

@log_request @require_auth def view(): ...

Use a single decorator that combines both behaviors.

Apply both decorators inside the function body using nested calls.

@require_auth @log_request def view(): ...

A system has a base class Animal with a method speak(). The team needs to create subclasses Dog and Cat that each provide their own speak() implementation. When a list of Animal objects is iterated, calling speak() should produce the correct sound for each type. Which design pattern achieves this?

Define speak() as a static method in each subclass.

Define speak() in each subclass, overriding the base class method.

Define speak() only in the base class and use type checking in the method.

Define speak() as a class method in the base class.

A developer is building a 'BankAccount' class and wants to protect the 'balance' attribute from direct external modification, but still allow it to be read and updated through methods. Which approach best achieves this?

Use a regular attribute 'balance' and document that it should not be modified directly.

Use a name-mangled attribute like '__balance' and provide getter and setter methods.

Use a property with a getter and setter, but store the value in a public attribute.

Use a class attribute 'balance' and update it through class methods.
