Question

为什么会出现错误“ TypeError：列表索引必须是整数或切片，而不是str”？？但是，如果我将列表中的值更改为整数，是否不会items.remove(items[1])只是删除索引位置1中的项目？

def choose_item():
    pick = int(input("Enter what item number you want [1-20]: "))
    store_item(pick)
    while pick < 1 or pick > 20:
        print("Not Valid")
        pick = input("Enter what item number you want [1-20]: ")


def store_item(pick):
    items =['1','1','1','1','1','2','2','2','2','2','3','3','3','3','3','4','4','4','4','4','5','5','5','5','5','5','5','5','5','5','6','6','6','6','6','7','7','7','7','7','8','8','8','8','8','9','9','9','9','9','9','9','9','9','9','10','10','10','10','10','11','11','11','11','11','12','12','12','12','12','13','13','13','13','13','14','14','14','14','14','15','15','15','15','15','16','16','16','16','16','17','17','17','17','17','18','18','18','18','18','19','19','19','19','19','20','20','20','20','20']
    if pick == 1:
        items.remove(items['1'])

choose_item()

您正在使用字符串作为整数，在这里items.remove（items ['1']），remove不能那样工作。选中此Difference between del, remove and pop on lists

带有列表的python TypeError
