class, __init__, self — the three keywords ai uses every time

Write a class called Score that:

• Takes no arguments to its __init__ (besides self).
• Sets self.points to 0 in __init__.
• Has a method add(self, n) that increases self.points by n.

Then create one instance, call .add(3) and .add(7), and print the final points.

Expected output:

10
