Example of class method and static method in Python

.py

class iPhone:
	iphone_list = ["3g", "3gs", "4", "4S", "5", "5s"]

	def __init__(self, model):
		self.model = model

	@classmethod
	def from_year(cls, year):
		return cls(iPhone.iphone_list[int(year) - 2008])

	@staticmethod
	def what_is_newest():
		return iPhone.iphone_list[len(iPhone.iphone_list) - 1]

	def __repr__(self):
		return self.model


a = iPhone("3g")
b = iPhone.from_year(2008)

print("Newest Model: "+iPhone.what_is_newest())
print("a has "+str(a))
print("b has "+str(b))
print("a==b: " + str(a == b))
print("a.model==b.model: " + str(a.model == b.model))

# Newest Model: 5s
# a has 3g
# b has 3g
# a==b: False
# a.model==b.model: True
