【问题描述】:
当我运行我的代码并进入游戏的战斗部分时,我会随机获得分配给我的角色攻击、防御、伤害和健康的值。但是,在他们的第一轮之后,他们一直获得相同的值并且无法重置。
例如,用户的攻击是一个从 4 到 11 的随机数。程序“滚动”5 并将其分配给变量 userAtk
userAtk = random.randint(4,11)
我假设每次循环运行时,它都会生成一个新值。 但它不是,每次我打印变量时,它的值都是第一次分配的。 我错过了什么吗?
下面是我的代码
import random

# This variable is the user's character name

【问题讨论】:
-
你不需要
` character for multiple line statements when parentheses are involved. For example, in your multiline print function calls you can remove the`。 -
另外,你应该看看 python 的string formatting。您可以使用它来缩短用于使用
+运算符构建字符串的所有行。 -
您似乎在寻找一种神奇的东西,每次您将其作为数字访问时,它都有不同的价值。你实际上可以创建这样一个类型,但是那里有很多混淆的可能性,这就是为什么 Python 没有给你这样一个内置的类型。特别是,
random.randint()返回;它只是随机选择一个常规的旧 int 并将其返回给您。
