【问题描述】：

    if b1a == "rock":
    print("you gave him a concussion and made the rock your new weapon")
    weapon = "rock"
else:
    print("you had a heart attack because you didn't pick one of the options")
    exit()

if b1a == "NIGERUNDAYO":
    weapon = "tommy gun"
    print("You ran so much that the beast got tired, then you took out a tommy gun and started shooting")
else:
    print("you had a heart attack because you didn't pick one of the options")
    exit()

if b1a == "slash":
    print("you slashed his face with a hatchet. ")
else:
    print("you had a heart attack because you didn't pick one of the options")
    exit()

它总是让我心脏病发作。

我是初学者，想知道是否有其他方法可以解决这个问题。

【问题讨论】：

你需要elif。
如果您是初学者，那么在这种情况下阅读一些有关 Python 的基础教程可能是一个很好的主意。您似乎遇到的问题应该被他们和许多其他有用的东西所涵盖。

【解决方案1】：

最好每次只使用elif 而不是if-else 构造。

if b1a == "rock":
    print("you gave him a concussion and made the rock your new weapon")
    weapon = "rock"
elif b1a == "NIGERUNDAYO":
    weapon = "tommy gun"
    print("You ran so much that the beast got tired, then you took out a tommy gun and started shooting") 
elif b1a == "slash":
    print("you slashed his face with a hatchet. ")
else:
    print("you had a heart attack because you didn't pick one of the options")
    exit()

【解决方案2】：

也许这个解决方案就足够了。

试试elif statements。

if b1a == "rock":
    print("you gave him a concussion and made the rock your new weapon")
    weapon = "rock"

elif b1a == "NIGERUNDAYO":
    weapon = "tommy gun"
    print("You ran so much that the beast got tired, then you took out a tommy gun and started shooting")
    exit()

elif b1a == "slash":
    print("you slashed his face with a hatchet. ")

else:
     print("you had a heart attack because you didn't pick one of the options")
     exit()
