Its much easier to respond to if you just copy n paste the code into the
email - as I've done below...

The 4 lines above should be inside the __init__() method, otherwise
you only get one person's birthday for the class not one per person..

Everything unique to an instance should be inside __init__()

This should probably be called check_age() or similar since age()
suggests that it returns the age. Its just a bit confusing.

And here we have a problem because you overwrite your method with data.
self.age is the method you are calling. By doing this you lose the method.

If you are getting a ValueError please include the full error text.
It contains lots of useful data.
