Answer 1

对于第一个RSI

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

和其他日期的相同方式。

对于所有RSI，您可以使用for-loop与.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
