have a list with values
test = ["mark","will","john"]
using for loop how to convert this into JSON like this
test =[{"name":"mark"},{"name":"john"},{"name":"will"}]
Tried this

print({"name":i})

1does your list only contains names or any other values you want to convert it into jsonShubham Shaswat– Shubham Shaswat2020-02-19 09:40:54 +00:00Commented Feb 19, 2020 at 9:40

Create a dictionary within a list comprehension:
test = ["mark","will","john"]
json_list = [{"name": n} for n in test]
same as:
json_list = []
for n in test:
json_list.append({"name" : n})
then dump to json:
import json
json.dumps(json_list)

import json
test =[{"name":"mark"},{"name":"john"},{"name":"will"}]
testJson = json.dumps(test)
print(testJson)

Hi and welcome to stackoverflow, and thank you for answering. While this code might answer the question, can you consider adding some explanation for what the problem was you solved, and how you solved it? This will help future readers to understand your answer better and learn from it.
functional way using map()
test = ["mark", "will", "john"]
toJson = lambda _name: {"name": _name} # this expression returns {"name": name} for every iterated "_name"
testJson = map(toJson, test)
for name in testJson:
print(name)
to print a list of a map object cast it to list, example list(testJson)
and you can replace toJson with your lambda expression to customize the result

>>> test = ["mark","will","john"]
>>> final=[]
>>> for i in test:
d=dict()
d['name']=i
final.append(d)
>>> final
>>>[{'name': 'mark'}, {'name': 'will'}, {'name': 'john'}]
