【问题描述】：

print("Please input your values")

strength = input("STRENGTH: ")
dexterity = input ("DEXTERITY: ")
constitution = input("CONSTITUTION: ")
intellegence = input("INTELLEGENCE: ")
wisdom = input("WISDOM: ")
charisma = input("CHARISMA: ")
sm = 0
dxm = 0
cm = 0
im = 0
wm = 0
chm = 0

if strength == 1:
    sm = -5
    return sm
elif strength == 2 or strength == 3:
    sm = -4
    return sm
elif strength == 4 or strength == 5:
    sm = -3
    return sm
elif strength == 6 or strength == 7:
    sm = -2
    return sm
elif strength == 8 or strength == 9:
    sm = -1
    return sm
elif strength == 10 or strength == 11:
    sm = +0
    return sm
elif strength == 12 or strength == 13:
    sm = +1
    return sm
elif strength == 14 or strength == 15:
    sm = +2
    return sm
elif strength == 16 or strength == 17:
    sm = +3
    return sm
elif strength == 18 or strength == 19:
    sm = +4
    return sm
elif strength == 20 or strength == 21:
    sm = +5
    return sm
elif strength == 22 or strength == 23:
    sm = +6
    return sm
elif strength == 24 or strength == 25:
    sm = +7
    return sm
elif strength == 26 or strength == 27:
    sm = +8
    return sm
elif strength == 28 or strength == 29:
    sm = +9
    return sm
elif strength == 30:
    sm = +10
    return sm

print(str(sm))

我不确定为什么打印时代码在值 sm 上输出 0。我已经尝试了很多事情，包括在 def modify(value, modifier): 中缩进 if、elif、elif、elif... 代码，但不幸的是没有奏效。

【问题讨论】：

您的输入是字符串，并且您正在与数值进行比较，等式总是错误的

【解决方案1】：

input 返回一个字符串。如果键入 1，strength 的值将变为 "1"，它不等于 1。

【解决方案2】：

代码应该是这样的

print("Please input your values")

strength = int(input("STRENGTH: "))

sm = 0
dxm = 0
cm = 0
im = 0
wm = 0
chm = 0

if strength == 1:
    sm -= 5

elif strength == 2 or strength == 3:
    sm -= 4

elif strength == 4 or strength == 5:
    sm -= 3

elif strength == 6 or strength == 7:
    sm -= 2

elif strength == 8 or strength == 9:
    sm -= 1

elif strength == 10 or strength == 11:
    sm += 0

elif strength == 12 or strength == 13:
    sm += 1

elif strength == 14 or strength == 15:
    sm += 2

elif strength == 16 or strength == 17:
    sm += 3

elif strength == 18 or strength == 19:
    sm += 4

elif strength == 20 or strength == 21:
    sm += 5

elif strength == 22 or strength == 23:
    sm += 6

elif strength == 24 or strength == 25:
    sm += 7

elif strength == 26 or strength == 27:
    sm += 8

elif strength == 28 or strength == 29:
    sm += 9

elif strength == 30:
    sm += 10

print(str(sm))

您在上传的代码中遇到的问题是
1）您存储在强度输入中，即str，稍后，您将其与int strength == 1进行比较，因此需要将其转换为int。 2）增加和减少的是= +和= -，需要是+= and -=。 3) sm 的返回不是必需的，因为您希望最后打印它而不是从函数返回值。

以strength == '1' 为例
