如何提示用户为列表中的每个值指定一个新名称？

Question

因此，我需要命名列表中从第一个用户输入创建的每个项目。 我的第一行代码如下：

num_assessment = int(input('How many assessments per student?'))

现在，我需要用户为列表中的每个项目命名；例如：

How many assessments per student?:2
What type of assessment was assessment 1? Essay
How many marks is the Essay worth? 30
What type of assessment was assessment 2 ? Test
How many marks is the Test worth? 70

我可以使用什么功能来执行此操作？你知道吗

Answer 1

带有for循环的字典是构造数据的一种方法。下面是一个例子。你知道吗

num_assessment = int(input('How many assesments per student?\n'))

data = {}

for i in range(1, num_assessment+1):
    data_type = input('What type of assessment was assessment {0}?\n'.format(i))
    data_marks = int(input('How many marks is the {0} worth?\n'.format(data_type)))
    data[i] = {'type': data_type, 'marks': data_marks}

示例

How many assesments per student?
2
What type of assessment was assessment 1?
essay
How many marks is the essay worth?
30
What type of assessment was assessment 2?
assignment
How many marks is the assignment worth?
50

结果

print(data)
{1: {'marks': 30, 'type': 'essay'}, 2: {'marks': 50, 'type': 'assignment'}}
