print price
return price

Python通常在一行上打印出dict等，这与API无关。如果您想为自己的观看打印得很好，请尝试：
from pprint import pprint
pprint(data)
或：
print json.dumps(data, indent=4)
答案 1 :(得分：1)
您需要知道解析它的响应格式。我看到你使用了requests.get()。
收到请求后
request = requests.get(...)
request.json()将返回JSON响应的dict对象。它看起来像（格式化后，used the codes like of @Alex）：
