不支持的操作数类型（S）为+：“功能”和“廉政”

Question

我想不通为什么我收到此错误：

Traceback (most recent call last): 
    File "C:/Users/tyler/Desktop/PycharmProjects/Arcade Game/AttackDirectory.py", line 63, in <module> 
    ThiefPdmg = randint(lambda x: (round(x*0.75)), lambda x: (round(x*1.00)))(Thief['stats']['Attack']) 
    File "C:\Python27\lib\random.py", line 242, in randint 
    return self.randrange(a, b+1) 
    TypeError: unsupported operand type(s) for +: 'function' and 'int' 

我还在学习Python和我在一个游戏的战斗系统上工作。我敢肯定，这些代码很粗糙，所以如果你有任何方法让它变得不那么粗糙，并且可能工作得更好，我会接受建议。

错误来自哪里？

randint [1]函数期望将int数字作为参数传递。相反，你正在传递看似不必要的lambda函数。例如，而不是randint(lambda x: round(x*0.25), lambda x: round(x*0.75))，只需要randint(round(x*0.25), round(x*0.75))即可。只有在需要传递function的东西时才使用lambda，就像回调一样。
