Question

我正在尝试获取此代码以基于用户输入的整数来打印降序或升至0的数字。在当前形式下，它根据正输入或负输入重复打印-1或1。我希望输出看起来与此类似。
请输入一个整数：
-6
顺序是：
-6
-5
-4
-3
-2
-1
0
序列的总和是-21。

Integer = int(input('Please enter an integer: '))
print ('The sequence is:')
if Integer < 0:
    while Integer != 0:
        New_int = Integer =+ 1
        print (New_int)
        Integer = Integer =+ New_int
    print ('The sum of the sequence is ',Integer)
elif Integer == 0:
    print (Integer)
    print ('The sum of the sequence is ',Integer)
else:
    while Integer != 0:
        New_int = Integer =- 1
        print (New_int)
        Integer = Integer =+ New_int
    print ('The sum of the sequence is ',Integer)

Answer 1

您的语法不正确，请尝试运行此语法：

Integer = int(input('Please enter an integer: '))
print ('The sequence is:')
if Integer < 0:
    while Integer != 0:
        Integer += 1
        print (Integer)
    print ('The sum of the sequence is ',Integer)
elif Integer == 0:
    print (Integer)
    print ('The sum of the sequence is ',Integer)
else:
    while Integer != 0:
        Integer -= 1
        print (Integer)
    print ('The sum of the sequence is ',Integer)

Answer 2

说实话，您的代码有很多问题，我会尝试解决其中的一些问题。

首先，按照惯例，大写字母保留用于类，所以我替换了大写字母。
第二，尝试对变量赋值使用更简单的表示法，似乎您感到困惑。
第三，您试图同时将整数转换为整数和列表/数组，因此您永远都无法得到总和，因此我将其分为两部分：

话虽如此，这保留了代码的逻辑性并起作用：

integer = int(input('Please enter an integer: '))
print ('The sequence is:')
sum_int= integer
if integer < 0:
    while integer != 0:

        new_int = integer + 1
        print (new_int)
        sum_int+= new_int
        integer =  new_int
    print ('The sum of the sequence is ',sum(int_list))
elif integer > 0:

    while integer != 0:
        new_int = integer - 1
        sum_int+= new_int
        print (new_int)
        integer = new_int
    print ('The sum of the sequence is ',sum(int_list))

elif integer == 0:
    print (integer)
    print ('The sum of the sequence is ',integer)

在循环的每次迭代中，您将new_int添加到sum_int，然后从第一个new_int值开始integer，这样就可以得出循环结束。

Answer 3

正如评论中提到的那样，您有几个语法错误和一些逻辑错误。

Integer = int(input('Please enter an integer: '))
print('The sequence is:')
sum = 0
if Integer < 0:
    while Integer != 0:
        sum += Integer
        print(Integer)
        Integer = Integer + 1
elif Integer == 0:
    print (Integer)
else:
    while Integer != 0:
        sum += Integer
        Integer -= 1
        print(Integer)

print('The sum of the sequence is ', sum)

Answer 4

我想这就是您想要做的：

Integer = int(input('Please enter an integer: '))
print ('The sequence is:')
Sum = Integer
print (Integer)
if Integer < 0:
    while Integer != 0:
        Integer += 1
        print (Integer)
        Sum += Integer
    print ('The sum of the sequence is ', Sum)
elif Integer == 0:
    print (Integer)
    print ('The sum of the sequence is ', Integer)
else:
    while Integer != 0:
        Integer -= 1
        print (Integer)
        Sum += Integer
    print ('The sum of the sequence is ', Sum)

所以输出将是：

Please enter an integer: -6
The sequence is:
-6
-5
-4
-3
-2
-1
0
The sum of the sequence is  -21

Answer 5

通过写Integer =+1，您说Integer变量为+1并且未递增。请查看此主题以获取更多信息：The difference between '+=' and '=+'? 正确的代码是：

Integer = int(input('Please enter an integer: '))
print ('The sequence is:')
if Integer < 0:
    while Integer != 0:
        New_int = Integer + 1
        print (New_int)
        Integer = Integer + New_int
    print ('The sum of the sequence is ',Integer)
elif Integer == 0:
    print (Integer)
    print ('The sum of the sequence is ',Integer)
else:
    while Integer != 0:
        New_int = Integer - 1
        print (New_int)
        Integer = Integer + New_int
    print ('The sum of the sequence is ',Integer)

您还可以简化打印变量。警告名称变量，请勿使用大写字母

Answer 6

因此，您对+ =运算符的操作感到困惑。你不必放完全New_int = Integer =+ 1。您的意思是New_int = Integer + 1

尽管如此，它完全不需要新变量New_int就能更好地工作：

以下内容适用于负数序列。

print ('The sequence is:')
int_list = []
if Integer < 0:
    while Integer != 0:
        print(Integer)
        int_list.append(Integer)
        Integer += 1
    print ('The sum of the sequence is ',sum(int_list))

（请注意我在代码外放置的总和和列表，您也可以使用变量current_sum = 0来添加它，并在每次迭代中将当前Integer添加到其中。

以上的输出是Integer = -6的以下内容：

The sequence is:
-6
-5
-4
-3
-2
-1
The sum of the sequence is  -21

请听有关将变量全部小写的建议。

我无法获取代码以打印出正确的信息。我只是永远打印一个数字
