[英]Get a value of key from JSON response in Python
I am accessing an API through a get request from which I get a response.我正在通过获取请求访问 API 并从中获得响应。
This is my code:这是我的代码:
import requests
import json
symbol = "AAPL"
end_point="https://api.polygon.io/v2/snapshot/locale/us/markets/stocks/tickers/"+symbol+"?apiKey=my_key"
r=requests.get(end_point).json()
print(r)
print(r['min'])
print(r)
returned: print(r)
返回:
{'request_id': '2735c0be51de7719fd99460fe8696080', 'status': 'OK', 'ticker': {'day': {'c': 172.93, 'h': 175.48, 'l': 172.37, 'o': 174.14, 'v': 65575561, 'vw': 174.0984}, 'lastQuote': {'P': 172.83, 'S': 3, 'p': 172.82, 's': 1, 't': 1644524332922450142}, 'lastTrade': {'c': None, 'i': '139592', 'p': 172.8199, 's': 2014, 't': 1644524331573573011, 'x': 4}, 'min': {'av': 65559987, 'c': 172.9, 'h': 173.14, 'l': 172.89, 'o': 173.09, 'v': 107429, 'vw': 173.0138}, 'prevDay': {'c': 176.28, 'h': 176.65, 'l': 174.9, 'o': 176.05, 'v': 71204538, 'vw': 175.8287}, 'ticker': 'AAPL', 'todaysChange': -3.46, 'todaysChangePerc': -1.963, 'updated': 1644524331573573011}}
but when I try to access the key "min", I get key error:但是当我尝试访问密钥“min”时,出现密钥错误:
KeyError: 'min'
This is super-simple.这是超级简单的。 What am I doing wrong?
我究竟做错了什么?
Please try:请试试:
r['ticker']['min']
the key min
is inside ticker
.关键
min
在ticker
内。 Do this:做这个:
r['ticker']['min']
