我如何将我的 int 更改为可迭代的内容？

如何解决我如何将我的 int 更改为可迭代的内容？

问题是得到这个输出： 运行 1

Enter number of aisles in supermarket: 100
Enter the aisle number to visit: 1
Enter the aisle number to visit: 8
Enter the aisle number to visit: 5
Enter the aisle number to visit: 4
Enter the aisle number to visit: 10
Enter the aisle number to visit: 0
The minimum distance is 26 units

到目前为止我的代码是

numberAisles = int(input("Enter number of Aisles in supermarket:"))
aisles = int(input("Enter the aisle number to visit:"))
if aisles == 0:
    print ("Not visiting any aisle")
else:
    while aisles > 0:
        aisles = int(input("Enter the aisle number to visit:"))
        if aisles == 0:
            iter (aisles)
            maxaisle = max(aisles)
            minaisle = min(aisles)
            B = (maxaisle + minaisle)//2
            mindis = ((maxaisle - B) + (B-minaisle))*2
            print (f"The minimum distance is {mindis} units")

错误信息是“TypeError: 'int' object is not iterable”

解决方法

请对您的代码进行一些更改以使用 list 及其方法：

numberAisles = int(input("Enter number of Aisles in supermarket: "))
aisles = []
aisles.append(int(input("Enter the aisle number to visit: ")))

i = 0
if aisles[0] == 0:
    print ("Not visiting any aisle")
else:
    while aisles[i] > 0:
        i += 1
        aisles.append(int(input("Enter the aisle number to visit: ")))
        if aisles[i] == 0:
            iter (aisles)
            maxaisle = max(aisles)
            minaisle = min(aisles)
            # B = (maxaisle + minaisle)//2
            # minDis = ((maxaisle - B) + (B-minaisle))*2
            minDis = ((maxaisle-minaisle))*2
            print (f"The minimum distance is {minDis} units")

此处无需将 B 定义为与 ((maxaisle-minaisle))*2 等效的两个注释行

您可以在循环内跟踪 maxaisle 和 minaisle，但在外部进行 dis calc。使代码更简洁。

maxaisle = 0
minaisle = 0
aisle = 1
numberAisles = int(input("Enter number of Aisles in supermarket:"))
while aisle > 0:
    aisle = int(input("Enter the aisle number to visit:"))
    maxaisle = max(maxaisle,aisle)
    minaisle = min(minaisle,aisle)

minDis = (maxaisle - minaisle)*2
if minDis == 0:
    print ("Not visiting any aisles")
else:
    print (f"The minimum distance is {minDis} units")
