[Python3] I made my first class! Feedback please.

Well, I just started a course on OOP with Python. Up until this point I had a lot of trouble grasping the concepts of, attributes and objects relating to classes but, I think I got it.  

Can any Python experts comment below and let me know what you think about my first useful class with methods.

# This is a test class made on 7/6/2017.

# Creates a class called User and sets, attributes for name and birth.

# Calculated how old user is and if their "oldenough" < 25 returns False.

# Alot of this is to just test things out

class User:

	#Birthday in yyyymmdd format

	def __init__(self, name, birth):

		self.name = name

		self.birth = birth

		self.byear = birth[0:4]

	#Checks year current year minus year born returns year born

	def yearsold(self):

		year = 2017

		age = year - int(self.byear)

		return age

	#returns False if younger than 25, and True for older than 25	

	def oldenough(self):

		if self.yearsold() < 25:

			return False

		else:

			return True

#Assigning an object called Ted to User with the required attributes

ted = User("Ted", "19941013")

rick = User("Rick", "18011230")

print(ted.name)

print(ted.byear)

print(ted.yearsold())

print(ted.oldenough())

print('.' * 25)

print(rick.name)

print(rick.byear)

print(rick.yearsold())

print(rick.oldenough())

#checks if the user is old enough 

#just wanted to test things out

if ted.oldenough() != True:

	print("Sorry {} you're only {} years old!".format(ted.name,ted.yearsold()))

else:

	print("Access Granted to: {}".format(ted.name))
