two Lists to Json Format in python

Question

I have two lists

a=["USA","France","Italy"]
b=["10","5","6"]

I want the end result to be in json like this.

[{"country":"USA","wins":"10"},
{"country":"France","wins":"5"},
{"country":"Italy","wins":"6"},
]

I used zip(a,b) to join two but couldn’t name it

Answer 1

Using list comprehension:

>>> [{'country': country, 'wins': wins} for country, wins in zip(a, b)]
[{'country': 'USA', 'wins': '10'},
 {'country': 'France', 'wins': '5'},
 {'country': 'Italy', 'wins': '6'}]

Use json.dumps to get JSON:

>>> json.dumps(
...     [{'country': country, 'wins': wins} for country, wins in zip(a, b)]
... )
'[{"country": "USA", "wins": "10"}, {"country": "France", "wins": "5"}, {"country": "Italy", "wins": "6"}]'

You can combine map with zip.

jsonized = map(lambda item: {'country':item[0], 'wins':item[1]}, zip(a,b))

Answer 3

You first have to set it up as a list, and then add the items to it

import json

jsonList = []
a=["USA","France","Italy"]
b=["10","5","6"]

for i in range(0,len(a)):
    jsonList.append({"country" : a[i], "wins" : b[i]})


print(json.dumps(jsonList, indent = 1))

Answer 4

In addition to the answer of ‘falsetru’ if you need an actual json object (and not only a string with the structure of a json) you can use json.loads() and use as parameter the string that json.dumps() outputs.

also for just combine two list to json format:

def make_json_from_two_list():
    keys = ["USA","France","Italy"]
    value = ["10","5","6"]
    jsons = {}
    x = 0
    for item in keys:
        jsons[item[0]] = value[x]
        x += 1
    return jsons

print(ake_json_from_two_list())

result>>>> {"USA":"10","France":"5","Italy":"6"}
