如何从用class A:
name = "Dog"
a1 = A()
a2 = A()
# These both change the value only for an instance
a1.name = "Cat"
a2.name += " is an animal"
print(a1.name, a2.name)
class B:
number = 0
b1 = B()
b2 = B()
# Again only changes value for an instance
b1.number = 2
print(b1.number, b2.number)
# This is the weird one.
class C:
lista = []
c1 = C()
c2 = C()
# Changes the value for BOTH/ALL instances.
c1.lista.append(5)
c2.lista.append(6)
print(c1.lista, c2.lista)
# But this one only changes the value for an instance.
c1.lista = [1, 2, 3]
print(c1.lista, c2.lista)
写的model获取transformation code？关于它有Epsilon Transformation Language (ETL)吗？
答案 0 :(得分：0)
使用Epsilon Haetae [1]，我们可以从ETL程序中获取模型。
