Python: converting a list of dictionaries to json

Question

I have a list of dictionaries, looking some thing like this:

list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}] 

and so on. There may be more documents in the list. I need to convert these to one JSON document, that can be returned via bottle, and I cannot understand how to do this. Please help. I saw similar questions on this website, but I couldn't understand the solutions there.

Answer 1

use json library

import json json.dumps(list) 

by the way, you might consider changing variable list to another name, list is the builtin function for a list creation, you may get some unexpected behaviours or some buggy code if you don't change the variable name.

Answer 2

import json  list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}] 

Write to json File:

with open('/home/ubuntu/test.json', 'w') as fout:     json.dump(list , fout) 

Read Json file:

with open(r"/home/ubuntu/test.json", "r") as read_file:     data = json.load(read_file) print(data) #list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]
