Question

我正在读一个文本文件然后创建一个python字典，之后我必须从该字典创建一个JSON文件。

这是一个示例文本文件：

伯兰州立大学的宿舍里有N名学生。他们每个人有时都想使用厨房，所以宿舍的负责人想出了一个厨房用的时间表，以避免冲突：

第一个学生在0时开始使用厨房，并且应该在A1时间之前完成烹饪。   第二个学生在A1时间开始使用厨房，并且应该在A2时间之前完成烹饪。   等等。

第N名学生在AN-1时开始使用厨房，并应在不迟于AN时完成烹饪   Berland的假期即将到来，所以今天这N名学生中的每一个都想煮一些煎饼。第i名学生需要Bi单位的时间来做饭。   学生们已经明白，可能不是所有人都能做到他们想要的一切。有多少学生可以在不违反时间表的情况下做饭？

输入

输入的第一行包含一个整数T，表示测试用例的数量。下面是T测试用例的描述。   每个测试用例的第一行包含一个表示学生数量的整数N.

第二行包含N个以空格分隔的整数A1，A2，...，AN，表示相应学生完成烹饪时的时刻。   第三行包含N个以空格分隔的整数B1，B2，...，BN，表示每个学生烹饪所需的时间。

输出

对于每个测试用例，输出一行，其中包含可以完成烹饪的学生人数。

约束

应包含您可能拥有的输入数据的所有约束。格式   它像：

1≤T≤10

1≤N≤10^ 4

0＆lt; A1＆lt; A2＆lt; ......＆lt; AN＆lt; 10 ^ 9

1≤Bi≤10^ 9

实施例

输入：

2   3

1 10 15

1 10 3

3

10 20 30

15 5 20

输出：

2

1

解释

示例案例1.

第一个学生有1个单位的时间 - 时刻0.这对她来说就足够了。第二个学生有9个单位的时间，但想要煮10个单位的时间，并且不适合及时。第三个学生有5个单位的时间，适合及时，因为需要只做3个单位的时间。

案例2。

每个学生有10个单位的时间，但只有第二个时间能够适应。

这是生成的JSON：

"descriptions": {
    "description0": "There are N students living in the dormitory of Berland State University. Each of them sometimes wants to use the kitchen, so the head of the dormitory came up with a timetable for kitchen's usage in order to avoid the conflicts:",
    "description1": "The first student starts to use the kitchen at the time 0 and should finish the cooking not later than at the time A1.",
    "description2": "The second student starts to use the kitchen at the time A1 and should finish the cooking not later than at the time A2.",

The second student has 9 units of time, but wants to cook for 10 units of time, and won't fit in time. The third student has 5 units of time and will fit in time, because needs to cook only for 3 units of time.",

}

如果您在json中看到描述16-19，您可以看到它被≤替换为 \ u2264 ，我想让这个json的文本与文本文件中的相同

以下是我如何创建这个json：

    data = {
    'uid': userId,
    'descriptions': description,
    'inputs': inputs,
    'outputs': outputs,
    'ex_inputs': example_input,
    'ex_outputs': example_output,
    'miscs': misc,
    'constraints': constraints
}
print(data)
# Writing Finalized JSON description files
with open('/Users/abdul/PycharmProjects/d2cApi/finalized/description_' + str(fid) + '.json', 'w') as f:
    f.write(json.dumps(data, indent=4))
return json.dumps(data)

我如何实现这一目标？

请帮帮我！

提前致谢！

Answer 1

如何使用ensure_ascii=False？

>>> d = {"descriptions": {"description16": "1 ≤ T ≤ 10"}}
>>> json.dumps(d)
'{"descriptions": {"description16": "1 \\u2264 T \\u2264 10"}}'
>>> json.dumps(d, ensure_ascii=False)
'{"descriptions": {"description16": "1 ≤ T ≤ 10"}}'

Answer 2

将encoding='utf-8'添加到文件的开头。

with open('/Users/abdul/PycharmProjects/d2cApi/finalized/description_' + str(fid) + '.json', 'w', encoding="utf-8") as f:

Answer 3

我将上述两个答案合并为：

# Writing Finalized JSON description files
with open('/Users/abdul/PycharmProjects/d2cApi/finalized/description_' + str(fid) + '.json', 'w', encoding="utf-8")\
        as f:
    f.write(json.dumps(data, indent=4, ensure_ascii=False))
return json.dumps(data)

我在打开文件时添加了encoding="utf-8"，并在将数据转储到json文件时添加了ensure_ascii=False。

JSON转储在Python 3
