Loading and parsing a JSON file with multiple JSON objects
(5 answers)
Closed 3 years ago.
I want to parse a file that contains multiple JSON objects that are not enclosed in an array and are separated only by a line break. The file has the following schema:
{"id":1,"firstName":"John","lastName":"Doe"}
{"id":2,"firstName":"Bob","lastName":"Smith"}
As far as I know, the standard approach using json.load() doesn't work here, because the objects are not enclosed in an array. So is there an elegant way to parse such a file in Python without modifying it?
If every json object is on its own line, you should be able to do something like
with open('/path/to/file') as data:
objects = [json.loads(line) for line in data]

Convert a bytes array into JSON format
(8 answers)
Closed 2 years ago.
new to python here. Been trying this for quite a while now; would really appreciate some help.
I thought to try my hand at pulling data from an api, and what i got is a very long dictionary ( or at least i think its an dictionary )
response = requests.get('https://api.coingecko.com/api/v3/finance_products')
print(response.content)
can anyone give me any pointers on how to manipulate the results ?
I can't call the dictionary.
First few characters of it :
b'[{"platform":"Binance Savings","identifier":"CCOCOS30DAYSS001","supply_rate_percentage":"6.0","borrow_rate_percentage":null,"number_duration":null,"length_duration":null,"start_at":0,"end_at":0,"value_at":0,"redeem_at":0},{"platform":"DDEX Lending","identifier": etc etc
i'm not sure why there is a b' at the front.
Sorry if this isn't a clear question.
You can use
response.json()
which decodes it immediatly to a json object. Documentation here

How to convert string representation of list to a list
(19 answers)
Closed 5 years ago.
I have some problems with using a list in python.
Right now, I open a .txt file with data, and read it into my python file.
However, when I put the input from the datafile into variable data and print this to check if it works or not, I see a lot of extra brackets which I don't want. Right now, it looks like:
["['sports','pizza','other']"]
and I want it to have it in a way like this:
['sports','pizza','other']
Can someone help me to get this work? Reason why I want it in a format like I mentioned above, is that I want to compare the list with another list, and that does not work in the format with the ]"]
I hope someone will help me.
Simply use eval function from Python.
>>> a = ["['sports','pizza','other']"]
>>> eval(a[0])
['sports', 'pizza', 'other']

Deserialize a json string to an object in python
(12 answers)
Closed 8 years ago.
I need to convert json string to python object. for example,
{
"person":{
"name":"aa",
"age":"12",
"address":{
"city":"cc",
"road":"kk"
}
}
}
there are two python class Person and Address used to generate python object. but I don't know how to map it.
You can easily convert the JSON string to a native Python dictionary with json.loads:
import json
d = json.loads(s)
It is not clear what arguments your Person and Address take, but if they take keyword arguments matching the dictionary content it could be as simple as:
d['address'] = Address(**d['address'])
p = Person(**d)
Where ** unpacks the dictionary into keyword arguments.
You can do this in a couple ways. One way is the simplejson literal translation. I would say the cleanest way of creating an extensible method is creating a class with that same structure.

How to join list of strings?
I have a couple of functions in a module to run. First, I have to use read() to read strings in a document and save it as new_string and run a function. Then, I need to read a document using readlines(). After running the first function like match = clean_passage(new_string) then match contains ['/n', 'asdf', 'dfg']. Now, I need them in a line as it is shown in the original document. So, asdf dfg. How can I convet match into a thing that contains strings in a similar fashion that we get when we read a document using readlines().
So far, to do this, I had to save it and then open it using readlines(), which takes time. Is there any way to do that using a simple command? Sorry if the explanation is not clear.
try this:
to_convert = ['/n', 'asdf', 'dfg']
original_line = " ".join(to_convert)
