Get data from python datastream api

vishal.kak

import DatastreamPy as dsws
ds=dsws.Datastream(username='****',password='****')

d = ds.get_data (tickers='BARC', fields=['P'], start='2018-01-01', end='2023-03-01', freq='W')

How can I retrieve price data from "d". I intend to store it in database but am not able to access data.

d returns None

I tried the query and the dataframe d is not None.

>>> d = ds.get_data (tickers='BARC', fields=['P'], start='2018-01-01', end='2023-03-01', freq='W')
>>> d
Instrument    BARC
Field            P
Currency         £
Dates
2018-01-01  203.13
2018-01-08  200.10
...            ...
2023-02-20  175.88
2023-02-27  172.64

[270 rows x 1 columns]

>>> d.info()
<class 'pandas.core.frame.DataFrame'>
Index: 270 entries, 2018-01-01 to 2023-02-27
Data columns (total 1 columns):
 #   Column        Non-Null Count  Dtype
---  ------        --------------  -----
 0   (BARC, P, £)  270 non-null    float64
dtypes: float64(1)

You can get the series data from it by accessing it like this -

>>> d['BARC', 'P', '£']
Dates
2018-01-01    203.13
2018-01-08    200.10
               ...
2023-02-20    175.88
2023-02-27    172.64
Name: (BARC, P, £), Length: 270, dtype: float64
