convert unlabeled list of tuples to json (string)

[masterAndreas]

Say i have a list of unlabeled tuples which i want to convert to JSON
Where each tuple is an object (of the same type) which represents a user
the first value of the tuple represents a 'username' and second a 'role'
Sample Input:

[('Andy', '001'), ('Off0', '010'), ('Pla0', '100'), ('Pla1', '100'), ('Pla2', '100'), ('Pla3', '100')]

Output:

Output:
[
	{
		"username": "Andy",
		"role": "001"
	},
	{
		"username": "Off0",
		"role": "010"
	},
	{
		"username": "Pla0",
		"role": "100"
	},
	{
		"username": "Pla1",
		"role": "100"
	},
	{
		"username": "Pla2",
		"role": "100"
	},
	{
		"username": "Pla3",
		"role": "100"
	},
]

Note: i do not care about the white spaces

i can convert one tuple with:

json.dumps({'username':list[0][0], 'role':list[0][1]})

but i do not understand to conbine all the tuples of the list together

Thanks!

P.S. i am python newbie, but i am familiar with the basic concepts (like syntax)

import json
users = [('Andy', '001'), ('Off0', '010'), ('Pla0', '100'), ('Pla1', '100'), ('Pla2', '100'), ('Pla3', '100')]
keys = ['username', 'role']

data = [dict(zip(keys, user)) for user in users]
json_data = json.dumps(data, indent=4)
print(json_data)

import json
users = [('Andy', '001'), ('Off0', '010'), ('Pla0', '100'), ('Pla1', '100'), ('Pla2', '100'), ('Pla3', '100')]
keys = ['username', 'role']

data = [dict(zip(keys, user)) for user in users]
json_data = json.dumps(data, indent=4)
print(json_data)

Thanks man!

Explaining what you did for anyone in the future who has this problem

data = [dict(zip(keys, user)) for user in users]

converts the (unlabeled) tuple to a dictionary (effectivly a named tuple)
and then

json_data = json.dumps(data, indent=4)

simply encode it

dictionary (effectivly a named tuple)

dict is not namedtuple! These are two very different container types

If you want to use namedtuple

import json
from collections import namedtuple
users = [('Andy', '001'), ('Off0', '010'), ('Pla0', '100'), ('Pla1', '100'), ('Pla2', '100'), ('Pla3', '100')]
User = namedtuple('User', 'username role')
print(User('Andy', '001'))
data = [User(*item)._asdict() for item in users]
json_data = json.dumps(data, indent=4)
print(json_data)

In my opinion simply using a dict is better.

would it be more accurate if I rephrased as

dictionary (effectively for our purposes, a pseudo named-tuple)
