how can I add index as key value in a list of dict in python?-CodePudding

I have a list like below -

[{'amount': 1100000, 'target': 120000, time': '2022-09-30T00:00:00.000Z'}, {'amount': 1100000, 'target': 120000, time': '2022-09-30T00:00:00.000Z'},
{'amount': 1100000, 'target': 120000, time': '2022-09-30T00:00:00.000Z'}]

Need to add index key and its value in these three records. Expected output -

[{'amount': 1100000, 'target': 120000, time': '2022-09-30T00:00:00.000Z','index':0}, {'amount': 1100000, 'target': 120000, time': '2022-09-30T00:00:00.000Z','index':1},
{'amount': 1100000, 'target': 120000, time': '2022-09-30T00:00:00.000Z','index':2}]

Please help.

Try:

lst = [
    {"amount": 1100000, "target": 120000, "time": "2022-09-30T00:00:00.000Z"},
    {"amount": 1100000, "target": 120000, "time": "2022-09-30T00:00:00.000Z"},
    {"amount": 1100000, "target": 120000, "time": "2022-09-30T00:00:00.000Z"},
]

for idx, d in enumerate(lst):
    d["index"] = idx

print(lst)

Prints:

[
    {
        "amount": 1100000,
        "target": 120000,
        "time": "2022-09-30T00:00:00.000Z",
        "index": 0,
    },
    {
        "amount": 1100000,
        "target": 120000,
        "time": "2022-09-30T00:00:00.000Z",
        "index": 1,
    },
    {
        "amount": 1100000,
        "target": 120000,
        "time": "2022-09-30T00:00:00.000Z",
        "index": 2,
    },
]
