Accessing value inside nested dictionary-CodePudding

Trying to access the value associated with the date_added key in a dictionary returned from coinmarketcap which I have named data_dict

The value which I am trying to retrieve is 2013-04-28T00:00:00.000Z

data_dict = {'status': {'timestamp': '2021-10-07T11:14:06.481Z', 'error_code': 0, 'error_message': None, 'elapsed': 10, 'credit_count': 1, 'notice': None}, 'data': {'1': {'id': 1, 'name': 'Bitcoin', 'symbol': 'BTC', 'category': 'coin', 'description': 'Bitcoin (BTC) is a cryptocurrency .

I have tried the following without any success....

extracted_date = data_dict['data']['date_added']

In fact, my attempt returns the following error....

KeyError: 'date_added'

I do not understand why this error is occuring

CodePudding user response：

extracted_date = data_dict['data']['1']['date_added']

CodePudding user response：

You actually have a double nested dict. Inside 'data' there is a dict named '1', in which the key 'date_added' can be found.

Try:

extracted_date = data_dict['data']['1']['date_added']
