How to convert a query string to valid json? [duplicate]

from urllib.parse import parse_qs

data = parse_qs('username=andrew&password=password1234')

>>> parse_qs('username=andrew&password=password1234')
{'username': ['andrew'], 'password': ['password1234']}

from urllib.parse import parse_qs

data = { k: v
    for k, vs in parse_qs('username=andrew&password=password1234').items()
    for v in vs
}

>>> { k: v
...     for k, vs in parse_qs('username=andrew&password=password1234').items()
...     for v in vs
... }
{'username': 'andrew', 'password': 'password1234'}

>>> print(dumps(data))
{"username": "andrew", "password": "password1234"}

import urllib.parse
import json
spam = 'username=andrew&password=password1234'
eggs = urllib.parse.parse_qsl(spam)
print(eggs)
foo = dict(eggs) # dict
print(foo)
bar =  json.dumps(foo) # JSON string
print(repr(bar))

[('username', 'andrew'), ('password', 'password1234')]
{'username': 'andrew', 'password': 'password1234'}
'{"username": "andrew", "password": "password1234"}'
