hello dear Community,
a class for storing contact data - Here is the code of a simple custom class which stores information about a person:
background: We start the class definition with the class keyword, followed by the class name and a colon. i think it is not bad to list any parent classes in between round brackets before the colon, but this class doesn’t have any, so i can leave them out. Inside the class body, we ve got two functions – these are our object’s methods.
1. The first method: is called __init__, which is a special method. When we call the class object, a new instance of the class is created, and the __init__ method on this new object is immediately executed with all the parameters that we passed to the class object. The purpose of this method is thus to set up a new object using data that we have provided.
The second method is a custom method which calculates the age of our person using the birthdate and the current date.
i want to store the data in a db or in a file
