输入一个数，打印这个数并打印从1开始到这个数的奇数偶数总和加奇数减偶数

下面为代码，还有完善的地方：

x = int(input(‘请输一个数:‘)) + 1
a = 0
list1 = []
list2 = []
sum = 0
for n1 in range(x):
    if n1 % 2 == 0:
        list1.append(n1)
        sum = sum - n1
    else :
        list2.append(n1)
        sum = sum + n1
    a = a + n1
print(n1)
print(‘偶数为：‘, list1)
print(‘奇数为：‘, list2)
print(‘1-和为：‘, a)
print(‘sum:‘,sum)
