Python类，试图掌握与其他类相关的函数一起创建类实例的概念

Question

请注意，这不是硬件或项目。在网上找到了一份旧考试，并认为应该很好理解进行了一些评论，但对此仍然很模糊。对于如何理解这一点的任何见解将不胜感激。

Answer 1

# a
X = City("Chicago", "Illinois")

# b - note this line of code would have to be inside of a function
return X.population

# c
X.county = "Cook"

# d - again, would need to be in a function
return X.state
