how to make a class in python
class Person: def __init__(self, _name, _age): self.name = _name self.age = _age def sayHi(self): print('Hello, my name is ' + self.name + ' and I am ' + self.age + ' years old!') p1 = Person('Bob', 25) p1.sayHi() # Prints: Hello, my name is Bob and I am 25 years old!
declare class python
# To create a simple class: class Shape: def __init__(): print("A new shape has been created!") pass def get_area(self): pass # To create a class that uses inheritance and polymorphism # from another class: class Rectangle(Shape): def __init__(self, height, width): # The constructor super.__init__() self.height = height self.width = width def get_area(self): return self.height * self.width
python define class
class uneclasse(): def __init__(self): pass def something(self): pass xx = uneclasse() xx.something()
