I'm trying to make a contacts app using classes in Python to get familiar with OOP. I want to have a function `delete()` inside the `Contact` class which deletes the object (sets the object/variable to `None`)

The code:

```
class Contact():
    def __init__(self, name, number, contact):
        self.name = name
        self.number = number
        self.contact = contact

    def delete(self):
        # delete object a
        return

a = Contact("test", 5358938, "a@gmail.com")
a.remove()
# a should now be None

```
