Managing Objects

[JoeDainton123]

Hello all

I was wondering if anyone could help shed some light on how to manage objects once they have been instantiated.

I have a class that creates a person that takes various attributes and uses 2 x methods, the code is as follows:-

from datetime import date

class Human():

    
    def __init__(self, name, sex, eyecolor, height, yearborn):
        self.name = name
        self.sex = sex
        self.eyecolor = eyecolor
        self.height = height
        self.yearborn = yearborn
        
        print("Object", self.name, self.sex, self.eyecolor, self.height, self.yearborn, "Has been created")
        
    
    def age(self):
        currentdate = date.today()
        a = currentdate.year - self.yearborn
        return a
    
    def display(self):
        print(self.name)
        print(self.sex)
        print(self.eyecolor)
        print(self.height)
        print(self.yearborn)

I create the object using the code:-

Tom = test.Human("Tom","Male", "Green",178,1989)

After the I have performed, for example, calculating the age then what do I with the object if I no longer need it - do I delete the object, can I safety forget about it - does it just sit in memory?

Also is there any way of determining how many objects have been created by a class?

Thank you.

You don't need to worry about managing objects if an object is no longer referenced anywhere it will get garbage collected.
