Question

我尝试了每种方法，观看了每个视频，并从Stack Overflow寻求解决方案。似乎没有任何作用。我的目标是创建仅包含原始数据的列表。 理想输出的示例： [date1, data1a, data1b, data1c, data1d, data1f, date2, data2a, data2b, etc,]我花在一些本来应该是微不足道的事情上的时间使我非常沮丧。我必须缺少一些东西。

下面是检索后刚打印的数据。

我正在使用的代码在下面，我在某些部分进行了注释，因为我尝试了许多不同的事情，这些注释指的是收到的错误以及为什么将代码更改为现在的代码。

#a wrapper I installed to help deal with the Alpha Vantage API, originally I coded everything myself but, after 
#realising that this worked for many others I thought I would limit the possible sources of errors that could
#come from me to help problem solve.
from alpha_vantage.timeseries import TimeSeries
ts = TimeSeries(key='*************')
# Get json object with the intraday data and another with  the call's metadata
data, meta_data = ts.get_daily('GOOGL')

print(data) #This works fine and prints the data in the expected format

print(type(data)) #This prints out "<class 'dict'>".

data_list = []
for date in data: # This will succesfully print out all of the dates(not broken up) if i leave out the below for
                  #  loop (which inforces the idea that each key is an attribute *pointing* towards information.
    for info in date: #When I try the "date.get" method, it states that "'str' object has no attribute 'get'.
        print(date[0])  #When I change it to date['1 open'] etc., it tells me that it must be an interger.
        print(date[1])  #When I use numbers it literally iterating through the name of the key as though
        print(date[2])  #it where a string. To out put one character at a time (and not even of the info I want to get).
        print(date[3])
        print(date[4])

循环的当前输出：

这一直持续到数据不再包含日期键为止。

Answer 1

您在这里面临两个问题：

问题＃1 是您正在解析的数据实际上不是键：值对象对，正如您的代码所暗示的那样；它实际上是一个元组数组。为什么？ Dunno-肯定不是最优雅的API设计。

问题2 是因为this issue, which is solved by using .iteritems() (or .items() for Python 3)。

尝试一下：

for o in data.iteritems():
    for date, data in {o[0]: o[1]}.iteritems():
        print(date, data['1. open'], data['2. high'], ....etc.)

遍历从API数据接收到的嵌套JSON不起作用
