In Python, a method is a function that belongs to an object. To call a method in a class, you need to create an instance of the class and then call the method using the dot notation. Here's an example:
class MyClass:
def hello(self):
print("Hello, world!")
my_object = MyClass()
my_object.hello()
In this example, we define a class called MyClass with a method called hello(). The hello() method simply prints "Hello, world!" to the console. We then create an instance of the MyClass class and assign it to the variable my_object. Finally, we call the hello() method on the my_object instance using the dot notation.
The output of the code will be:
Hello, world!
Here's another example where we pass arguments to the method:
class Rectangle:
def calculate_area(self, width, height):
return width * height
my_rect = Rectangle()
area = my_rect.calculate_area(5, 10)
print(area)
In this example, we define a class called Rectangle with a method called calculate_area(). The calculate_area() method takes two arguments: width and height. The method multiplies them together and returns the result. We then create an instance of the Rectangle class and assign it to the variable my_rect. Finally, we call the calculate_area() method on the my_rect instance, passing in the values 5 and 10 for the width and height arguments, respectively. We store the result in a variable called area and print it to the console.
The output of the code will be:
