异常和输出

Question

我在调用我的函数时遇到了问题，我收到了错误的输出，我将在后面的文本中解释

以下是我正在使用的资源：

Main_Building=[10,12,14,17,21,25,30,36,43,52,62,74,89,107,128,154,185,222,266,319,383,460,552,662,795,954,1145,1374,1648,1978]

这是我的密码：

def buildings(points):
    for i in range(0,30):
        try:
            if Main_Building[i]>=points:
                del Main_Building[i:]
            if Barracks[i]>=points:
                del Barracks[i:]
            if Stables[i]>=points:
                del Stables[i:]
            if Workshop[i]>=points:
                del Workshop[i:]
            if Blacksmith[i]>=points:
                del Blacksmith[i:]
            if Market[i]>=points:
                del Market[i:]
            if Axe[i]>=points:
                del Axe[i:]
            if Clay_Pit[i]>=points:
                del Clay_Pit[i:]
            if Mine[i]>=points:
                del Mine[i:]
            if Settler_House[i]>=points:
                del Settler_House[i:]
            if Warehouse[i]>=points:
                del Warehouse[i:]
            if Wall[i]>=points:
                del Wall[i:]                  
        except IndexError:
            continue

问题是，当谈到铁匠的条件，它看起来在我看来，条件只是通过，和其他继续墙条件相同。条件是确定在何处停止并删除列表的其余部分以供进一步使用。列表的长度不同，所以我使用了简单的exception，当它超出范围时，它只是跳过并继续下一个条件

def建筑物（100）时的建议输出：

Blacksmith=[19,23,27,33,39,47,57,68,82,98]

实际输出是整个列表，没有任何变化。这同样适用于持续状态

我尝试的是：

1. 我试图重新启动Python，但不幸的是，没有成功

2. 如果我把变量名拼错了

3. 每种情况下都要重做间隔

也许是解决方法，但不是有效的，加上每个条件尝试例外？（在我看来不是一个好主意）

为什么它跳过了条件

谢谢你的帮助和时间

Answer 1

Continue将返回到当前循环的开头并获取下一个索引。这意味着，如果错误发生一半，则跳过最后一半。时间也相当长。这是我的解决办法

data = [Main_Building, Barracks, Stables, Workshop, Blacksmith, Market, Axe, Clay_Pit, Mine, Settler_House, Warehouse, Wall]
def buildings(points):
    for building in data: # loop through each building seperately, shortens code and removes arbitrary loop number
        for point in building: # loop through each buildings index, same as your code
            if point >= points:
                del building[building.index(point):]
buildings(20)
print data

Answer 2

如果在try-except之间发生任何错误，Python将传递或继续try-except之间的所有代码

try:
    a = int(input("integer: "))
    print("print this")
    print("print that")
except:
    pass

输出：

>>> 
integer: ab
>>>

看到print this和print that没有打印出来。你应该一个接一个地抓住错误

try:
    a = int(input("integer: "))
except:
    pass
print("print this")
print("print that")

>>> 
integer: ab
print this
print that
>>>
