Converting Python Dictionary to JSON Array

Question

I currently have a Python Dictionary that looks something like this:

OrderedDict([('2017-07-24', 149.7619), ('2017-07-25', 150.4019), ('2017-07-26', 151.1109), ...

that I am converting to JSON like so:

one_yr = json.dumps(priceDict)

Currently I am adding values to the dictionary from an SQL query by looping through it like so:

for i in query:
    date = i[0] 
    close = i[1]
    priceDict[date] = close

The problem is that this returns a JSON object, that i then have to convert to a JSON array.

I am wondering if I can just convert my Python Dictionary to a JSON array directly? Thanks.

Answer 1

json.dumps(list(priceDict.items()))

But why do you have an OrderedDict in first place? If you pass the same list you passed to OrderedDict to json.dumps it will generate your array:

json.dumps([('2017-07-24', 149.7619), ('2017-07-25', 150.4019),....])

No need for OrderedDict in this case

Answer 2

If you want to convert a Python Dictionary to JSON using the json.dumps() method.

`

import json 
from decimal import Decimal
d = {}
d["date"] = "2017-07-24"
d["quantity"] = "149.7619"
print json.dumps(d, ensure_ascii=False)

`

Answer 3

I removed the OrderedDict but kept all the other data, I think I understand the request. See if this works for you:

import json

my_dict = ([('2017-07-24', 149.7619), ('2017-07-25', 150.4019), ('2017-07-26', 151.1109)])

print(json.dumps(my_dict, indent=4, sort_keys=True))
