python index json array-CodePudding

I have a json file with 15000 lines that looks like this;

{
    "address": [
        "user address"
    ]
}{
    "purchase": [
        "details"
    ]
}{
    "info1": [
        "some information",
        "other information",
        "more information"
    ],
    "info2": [
        "something else"
    ]
}

I want to do something like:

f = open('my_file.json',)
data = json.load(f)
print(data[2])

In which index[2] would print everything between the last set of curly brackets so:

{
    "info1": [
        "some information",
        "other information",
        "more information"
    ],
    "info2": [
        "something else"
    ]
}

However I get error: raise JSONDecodeError("Extra data", s, end)

It works if I make it a string, something like: my_str = '[{"address": "user address"}, {"info1": "some information", "more information"}]' print(my_str[2])

Is it possible to read json file as above and print [2]?

Based on below comment, if I do something like this:

with open('my_file.json', 'r') as f:
my_list = list(f)
values_list = list(my_list)
a_value = values_list
print(a_value[10])

It prints "some information".

CodePudding user response：

json.load and json.loads need to have a correct JSON, from start to finish. Your file is not a correct JSON file; it seems it is a number of JSON documents concatenated with each other. To read it, you will have to be a bit more low-level:

with open('my_file.json', 'rt') as f:
    json_doc = f.read().strip()

decoder = json.JSONDecoder()
data = []
while json_doc:
    value, cont = decoder.raw_decode(json_doc)
    data.append(value)
    json_doc = json_doc[cont:]

print(data[2])
# => {'info1': ['some information', 'other information', 'more information'], 'info2': ['something else']}
