Question

我添加了一段新的代码，现在当我运行我的程序龟图形崩溃时。我没有在空闲时收到运行时错误，所以我不知道要修改什么来修复它

当我实现gotoFire（）函数时，崩溃才刚刚开始。我无法删除它，因为它对该程序的操作至关重要！

import turtle
import math
NUMBER_OF_LICENSES=10

def goodbyeMessage():
    print("Thank you for using the program!")

def getInfo():
    fire_Direction=math.radians(float(input("Please input the angle in degrees of the fire quickly!")))
    fire_Distance=float(input("Please input the distance of the fire ~VERY~ quickly (input a number between 1 and 5)"))
    return fire_Direction,fire_Distance


def announceDirections(horizontolDirection,verticalDirection):

    sideOfFireHouseToLeaveFrom=[]

    if horizontolDirection < 0:
        print("The fire is %d streets to the west of the firehouse!" %horizontolDirection)
        sideOfFireHouseToLeaveFrom += 'west'
    elif horizontolDirection > 0:
        print("The fire is %d streets to the east of the firehouse!" %horizontolDirection)
        sideOfFireHouseToLeaveFrom += 'east'
    else:
        sideOfFireHouseToLeaveFrom += 'void'

    if verticalDirection < 0:
        print("The fire is %d streets to the south of the firehouse!" %verticalDirection)
        sideOfFireHouseToLeaveFrom += 'south'
    elif verticalDirection > 0:
        print("The fire is %d streets to the north of the firehouse!" %verticalDirection)
        sideOfFireHouseToLeaveFrom += 'north'
    else:
        pass

    if verticalDirection == 0 and horizontolDirection == 0:
        print("The firehouse is on fire!")
        sideOfFireHouseToLeaveFrom += 'void' + 'void'

    return sideOfFireHouseToLeaveFrom

def gotoFire(horizontolDirection,verticalDirection,sideOfFireHouseToLeaveFrom):



    if sideOfFireHouseToLeaveFrom[0] == "east":

    sideOfFireHouseToLeaveFrom = announceDirections(horizontolDirection,verticalDirection)

    gotoFire(horizontolDirection,verticalDirection,sideOfFireHouseToLeaveFrom)

Answer 1

您将字符列表传递给sideOfFireHouseToLeaveFrom

的gotoFire参数

例如：

['v', 'o', 'i', 'd', 'n', 'o', 'r', 't', 'h']

这似乎不正确。我不认为你的程序崩溃了。它只是没有做任何事情，因为if条件都是False

回顾过去，我们发现坏数据似乎来自announceDirections。因为您正在尝试将字符串添加到列表中。

>>> sideOfFireHouseToLeaveFrom=[]
>>> sideOfFireHouseToLeaveFrom += 'west'
>>> sideOfFireHouseToLeaveFrom
['w', 'e', 's', 't']

您可能应该使用sideOfFireHouseToLeaveFrom.append('west')等

>>> sideOfFireHouseToLeaveFrom=[]
>>> sideOfFireHouseToLeaveFrom.append('west')
>>> sideOfFireHouseToLeaveFrom
['west']
