如何在我的python请求中添加quandl Api密钥

Question

我已经建立了一个私人quandl帐户并收到了quandl Api密钥，但是如何在python中将密钥添加到我的请求中呢？

我的代码：

import pandas as pd 
import quandl 

df = quandl.get('EOD/V')
print(df.head())

错误：

Traceback (most recent call last):
  File "C:\Users\qasim\Documents\python_machine_learning\regression.py", line 4, in <module>
    df = quandl.get('EOD/V')
  File "C:\Python27\lib\site-packages\quandl\get.py", line 48, in get
    data = Dataset(dataset_args['code']).data(params=kwargs, handle_column_not_found=True)
  File "C:\Python27\lib\site-packages\quandl\model\dataset.py", line 47, in data
    return Data.all(**updated_options)

Answer 1

在“ 配置”文档部分，您可以使用以下命令进行设置ApiConfig.api_key：

import quandl
quandl.ApiConfig.api_key = 'tEsTkEy123456789'

另外，从quandl python doc，您可以在get方法中定义其他可选参数：

：param str api_key：除非指定了api_key，否则下载限制为50次

因此，您还可以使用：

df = quandl.get('EOD/V', api_key='tEsTkEy123456789')
