Question

我尝试使用以下代码在Python中打印变量：

from time import sleep
import random

class Hero:
    def __init__(self,name):
        self.name = name

        if name == "rock":
            self.health = 50
            self.attack = 10

        elif name == "paper":
            self.health = 70
            self.attack = 7

        elif name == "scissors":
            self.health = 100
            self.attack = 5

    def dmg(self, other):
        other.ehealth -= self.attack

start = 1

while start == 1:
    name = input("Pick a class [rock/paper/scissors]")

    if name != "rock" or "paper" or "scissors":
        print ("That player does not exist. Try again.")
        start = 1

    else:
        start = 1

    player = Hero(name)
    enemyName = ["erock", "epaper", "escissors"]
    ename = random.choice(enemyName)

    print ("Your character is", name, "which comes with", self.health, "health, and", self.attack, "attack.")
    print("")

    sleep(1)

    print ("Your enemy is", ename, "which comes with", ehealth, "health, and", eattack, "attack.")

我无法找到一种方法来访问和打印变量＆＃34; self.health＆＃34;在＆＃34; Hero＆＃34;类。我可以访问＆＃34; name＆＃34;正好。也许它是在if声明下的事实？有人可以帮助我吗？

Answer 1

self只是方法中使用的参数名称。不要在方法之外使用它。

要访问变量，请使用对象名称（player）来引用它们，如下所示

player.health

您正在打印的name变量“有效”，因为它不是来自对象。您也应该使用相同的表示法来访问它：

player.name

如何在课程中打印变量＆＃39;如果声明？
