Question
Write a Rectangle class in Python language, allowing you to build a rectangle with length and width attributes.
Solution
Sure, here is a simple implementation of a Rectangle class in Python:
class Rectangle:
def __init__(self, length, width):
self.length = length
self.width = width
In this class, the __init__ method is a special method that Python calls when it instantiates an object using the definitions found in your class. Python's __init__ method is what's known as a constructor in other programming languages.
Here's how it works:
selfis a reference to the current instance of the class and is used to access variables that belongs to the class. It does not have to be namedself, you can call it whatever you like, but it has to be the first parameter of any function in the class.lengthandwidthare the parameters we pass to the__init__method. We use these parameters to set the initial state of our object, i.e., to create a rectangle with a certain length and width.
You can now create a new object of the Rectangle class like this:
my_rectangle = Rectangle(10, 5)
This will create a new rectangle with a length of 10 and a width of 5. You can access these attributes like this:
print(my_rectangle.length) # prints: 10
print(my_rectangle.width) # prints: 5
