格式化几乎成为json-fi

Question

我是Python初学者，正在阅读一个包含以下内容的文件：

{"quotes":["I could calculate your chance of survival, but you won't like it.","I'd give you advice, but you wouldn't listen. No one ever does.","I ache, therefore I am.","I've seen it. It's rubbish. (About a Magrathean sunset that Arthur finds magnificent)","Not that anyone cares what I say, but the Restaurant is on the other end of the universe.","I think you ought to know I'm feeling very depressed.","My capacity for happiness,\" he added, \"you could fit into a matchbox without taking out the matches first.","Arthur: \"Marvin, any ideas?\" Marvin: \"I have a million ideas. They all point to certain death.\"","\"What's up?\" [asked Ford.] \"I don't know,\" said Marvin, \"I've never been there.\"","Marvin: \"I am at a rough estimate thirty billion times more intelligent than you. Let me give you an example. Think of a number, any number.\" Zem: \"Er, five.\" Marvin: \"Wrong. You see?\"","Zaphod: \"Can it Trillian, I'm trying to die with dignity. Marvin: \"I'm just trying to die.\""]}*

正如您所看到的，它几乎是一个json文件，但是有一些额外的字符，比如：[\。你知道吗

任务：格式化文件内容，以便我可以访问单独的引号并打印随机引号。你知道吗

我可以试试这样的

jsonfile = open(INPUT, "r")
jsonobject = json.load(jsonfile)
someString = "\n\"{quotes}\"\n".format(quotes=jsonobject["quotes"])

它将从字符串中去掉{quotes:}。虽然还保留了其他不需要的字符，我也尝试过单独使用string.replace并在循环中使用，但它并没有给出我想要的结果。你知道吗

例如：holder = someString.replace("[\]", '')

格式化完成后，我想我应该使用一个循环并尝试使用random.string的随机模块？你知道吗

Answer 1

这应该按原样工作。你知道吗

import json
import random
file = open(<path to your file>,'r')
i = json.load(file)
#print a random quote
print i['quotes'][int(random.randrange(0,len(i['quotes'])-1))]

Answer 2

您已经有了有效的JSON数据。\"是转义引号（因此它是字符串值的一部分），而[...]是JSON数组（类似于Python列表）。你知道吗

只需将数据加载为JSON：

>>> import json
>>> jsondata = r'''{"quotes":["I could calculate your chance of survival, but you won't like it.","I'd give you advice, but you wouldn't listen. No one ever does.","I ache, therefore I am.","I've seen it. It's rubbish. (About a Magrathean sunset that Arthur finds magnificent)","Not that anyone cares what I say, but the Restaurant is on the other end of the universe.","I think you ought to know I'm feeling very depressed.","My capacity for happiness,\" he added, \"you could fit into a matchbox without taking out the matches first.","Arthur: \"Marvin, any ideas?\" Marvin: \"I have a million ideas. They all point to certain death.\"","\"What's up?\" [asked Ford.] \"I don't know,\" said Marvin, \"I've never been there.\"","Marvin: \"I am at a rough estimate thirty billion times more intelligent than you. Let me give you an example. Think of a number, any number.\" Zem: \"Er, five.\" Marvin: \"Wrong. You see?\"","Zaphod: \"Can it Trillian, I'm trying to die with dignity. Marvin: \"I'm just trying to die.\""]}'''
 >>> data = json.loads(jsondata)
 >>> data
 {'quotes': ["I could calculate your chance of survival, but you won't like it.", "I'd give you advice, but you wouldn't listen. No one ever does.", 'I ache, therefore I am.', "I've seen it. It's rubbish. (About a Magrathean sunset that Arthur finds magnificent)", 'Not that anyone cares what I say, but the Restaurant is on the other end of the universe.', "I think you ought to know I'm feeling very depressed.", 'My capacity for happiness," he added, "you could fit into a matchbox without taking out the matches first.', 'Arthur: "Marvin, any ideas?" Marvin: "I have a million ideas. They all point to certain death."', '"What\'s up?" [asked Ford.] "I don\'t know," said Marvin, "I\'ve never been there."', 'Marvin: "I am at a rough estimate thirty billion times more intelligent than you. Let me give you an example. Think of a number, any number." Zem: "Er, five." Marvin: "Wrong. You see?"', 'Zaphod: "Can it Trillian, I\'m trying to die with dignity. Marvin: "I\'m just trying to die."']}
>>> from pprint import pprint
>>> pprint(data)
{'quotes': ["I could calculate your chance of survival, but you won't like it.",
            "I'd give you advice, but you wouldn't listen. No one ever does.",
            'I ache, therefore I am.',
            "I've seen it. It's rubbish. (About a Magrathean sunset that "
            'Arthur finds magnificent)',
            'Not that anyone cares what I say, but the Restaurant is on the '
            'other end of the universe.',
            "I think you ought to know I'm feeling very depressed.",
            'My capacity for happiness," he added, "you could fit into a '
            'matchbox without taking out the matches first.',
            'Arthur: "Marvin, any ideas?" Marvin: "I have a million ideas. '
            'They all point to certain death."',
            '"What\'s up?" [asked Ford.] "I don\'t know," said Marvin, "I\'ve '
            'never been there."',
            'Marvin: "I am at a rough estimate thirty billion times more '
            'intelligent than you. Let me give you an example. Think of a '
            'number, any number." Zem: "Er, five." Marvin: "Wrong. You see?"',
            'Zaphod: "Can it Trillian, I\'m trying to die with dignity. '
            'Marvin: "I\'m just trying to die."']}
>>> import random
>>> print(random.choice(data['quotes']))
I've seen it. It's rubbish. (About a Magrathean sunset that Arthur finds magnificent)
>>> print(random.choice(data['quotes']))
I ache, therefore I am.

在上面的演示中，我使用^{} function从列表中随机选取一个引号。你知道吗

唯一缺少的是马文的摇篮曲，这是我最喜欢的马文的话语：

Now the world has gone to bed
Darkness won't engulf my head
I can see by infra-red
How I hate the night

Now I lay me down to sleep
Try to count electric sheep
Sweet dream wishes you can keep
How I hate the night
