What are class methods, static methods, and instance methods? (AI)

Question 1

What are instance methods?

Answer 1

• Work with both the class and individual instances
• Accept the self keyword
• Used for operations on attributes, like getters and setters
• Example: def double_value(self): self.value *= 2
• Call Type: my_instance.some_method()

Instance methods are essential for manipulating instance-specific data.

Question 2

What are class methods?

Answer 2

• Associated with the entire class
• Use the cls keyword instead of self
• Employed for operations pertaining to the class as a whole
• Example: @classmethod def initialize(cls, value): cls.class_variable = value
• Call Type: MyClass.some_method()

Class methods can also be called through an instance, but this is not recommended.

Question 3

What are static methods?

Answer 3

• Defined within the scope of the class
• Do not require access to instance or class attributes
• Used as helper functions or for independent operations
• Example: @staticmethod def is_valid_email(email): return True
• Call Type: MyClass.some_method()

Static methods are versatile and can be called through both the class and instances.
