解决方案

首先RSI

data['Technical Analysis: RSI']['2021-10-13']['RSI']

和其他日期一样。

对于所有RSI你可以使用for-loop.values()或.items()

for date, values in data['Technical Analysis: RSI'].items():
    print(date, values['RSI'])

data = {
    'Meta Data': {
        '1: Symbol': 'ABMD',
        '2: Indicator': 'Relative Strength Index (RSI)',
        '3: Last Refreshed': '2021-10-13',
        '4: Interval': 'weekly',
        '5: Time Period': 10,
        '6: Series Type': 'open',
        '7: Time Zone': 'US/Eastern Time'
    },
    'Technical Analysis: RSI': {
        '2021-10-13': {'RSI': '50.5159'},
        '2021-10-08': {'RSI': '44.3446'},
        '2021-10-01': {'RSI': '55.6364'},
        '2021-09-24': {'RSI': '58.2600'},
        '2021-09-17': {'RSI': '63.0876'},
        '2021-09-10': {'RSI': '68.3045'},
        '2021-09-03': {'RSI': '65.3299'},
        '2021-08-27': {'RSI': '61.9752'},
        '2021-08-20': {'RSI': '52.7723'},
        '2021-08-13': {'RSI': '64.7634'},
    }
}

print('First:', data['Technical Analysis: RSI']['2021-10-13']['RSI'])

print('--- all ---')
for date, values in data['Technical Analysis: RSI'].items():
    print(date, '|', values['RSI'])

结果：

First: 50.5159
--- all ---
2021-10-13 | 50.5159
2021-10-08 | 44.3446
2021-10-01 | 55.6364
2021-09-24 | 58.2600
2021-09-17 | 63.0876
2021-09-10 | 68.3045
2021-09-03 | 65.3299
2021-08-27 | 61.9752
2021-08-20 | 52.7723
2021-08-13 | 64.7634
