class Student(Person):

def init(self, name, age, student_id):

super().init(name, age)

self.student_id = student_id

def say_hello(self):

print(f"Hello, my name is {self.name}, I'm {self.age} years old and my student ID is {self.student_id}")

Output:

student = Student("Mike", 20, 12345)

student.say_hello()

In this example, we are creating a new class called Student that inherits from the Person class. The Student class adds a new attribute called student_id, and overrides the say_hello method to include the student_id in the output. We then create an object of the Student class and call the say_hello method.

2.2.2 Functional Programming

Python also supports functional programming concepts, such as higher-order functions, lambda functions, and map/reduce/filter functions.

- Higher-order functions: A higher-order function is a function that takes another function as an argument or returns a function as its result. For example:

def apply_function(f, x):

return f(x)

def square(x):

return x * x

result = apply_function(square, 2)

print(result)
