IndexError ::::列表索引超出范围

问题描述

嗨,这是我的代码,我不知道为什么收到这种错误

x = int(input())
n = [int(i) for i in input().split()]

middle = n[int((x - 1) / 2)

even = 0
odd = 0
for number in n:
    if number % 2 == 0:
        even += number
    else:
        odd += number

answer = even * odd + middle ** 2

print("{} x {} + {}^2 = {}".format(even,odd,middle,answer))

解决方法

由于n是用户输入的列表值的最小数目,因此会产生诸如IndexError: list index out of range之类的错误。

由于您的意图是使n具有比用户输入的最小位数更多的值,所以我在列表迭代中添加了.range()

这是修改后的代码:

x = int(input("Put in a number: "))
n = [int(i) for i in range(int(input("Put in another number: ")))]

middle = n[int((x - 1) / 2)]

even = 0
odd = 0
for number in n:
    if number % 2 == 0:
        even += number
    else:
        odd += number

answer = even * odd + middle ** 2

print("{} x {} + {}^2 = {}".format(even,odd,middle,answer))
