什么是属性？ 它如何“持有”价值？

Question

What does it mean for an attribute to hold something, and how is it executed in code?

More specifically, what exactly is an attribute in OOP Python? How can it hold a certain value, for example, "Jack"? Is an attribute similar to a variable? Some questions I'm wondering.

Answer 1

An attribute of a class or object is any of the member items: a method, a variable, etc. In this case, it's a variable. From this, I assume that you know what it means to hold a value.

Get rid of the string face attribute; this is merely the display rendition of the value. Store those renditions in a list or dict, and encapsulate that within your display method. For instance:

face_image = {
    1: ' ------\n|     |\n| o |\n|     |\n ------',
    2: ' ------\n| o   |\n|   |\n|   o |\n ------',
    ...

... and when you need it ...

print(face_image[self.value])

Does that get you moving?
