Converting list of lists to dictionary of dictionaries

Question

I have a list of strings like the following

string_list = ['''{"no" : 1, "name": "John Doe", "address": "123, Einstein St, SA, 28372"}''', '''{'no" : 1, "name": "John Denver", "address": "454, BohrSt, SA, 64584"}''']

I am trying to convert each string in the list into a dictionary and append it to a dictionary.

import json
newdict = {}
for string in string_list:
    new = json.loads(string)
    newdict.update(new)

but it is producing an error:

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

But if I do,

new = json.loads(string_list[1])

It works. And gives the type of new as <class 'dict'> . How can I solve this?

I think this one maybe you need

• use json.loads to convert the element of string_list to dict
• convert list of lists to dictionary of dictionaries by dict comprehension

code:

import json
string_list = ['{"no" : 1, "name": "John Doe", "address": "123, Einstein St, SA, 28372"}', '{"no" : 1, "name": "John Doe", "address": "123, Einstein St, SA, 28372"}']
print({idx:json.loads(data) for idx,data in enumerate(string_list)})

result:

{
    0: {"no": 1, "name": "John Doe", "address": "123, Einstein St, SA, 28372"},
    1: {"no": 1, "name": "John Doe", "address": "123, Einstein St, SA, 28372"},
}
