I am trying to generate REST API JSON format for a particular record in this below example I have chosen 2nd row:

    import pandas as pd
    sasdt = pd.read_sas("c:\hmeq.sas7bdat")
    dfs = [] # holds data chunks
    dfs2=sasdt.loc[2]
    for chunk in sasdt:
        print('{"name":"',chunk,'_","value":',)

I am unable to generate my desired output something like this: Could you please help me in this

Answer 1

Try this following:

import pandas as pd
import numpy
import json

sasdt = pd.read_sas('airline.sas7bdat')
dfs2 = sasdt.loc[2]

# avoid json.dumps raise "TypeError: Object of type 'int64' is not JSON serializable"
dfs2_values = [int(i) if type(i) == numpy.int64 else i for i in dfs2]

inputs = pd.DataFrame({'name':dfs2.index.to_list(), 'value':dfs2_values}).to_dict(orient='records')
json.dumps({'inputs':inputs})

You will get output like this:

'{"inputs": [{"name": "YEAR", "value": 1950.0}, {"name": "Y", "value": 1.569000005722046}, {"name": "W", "value": 0.27799999713897705}, {"name": "R", "value": 0.3156999945640564}, {"name": "L", "value": 1.3880000114440918}, {"name": "K", "value": 0.5730000138282776}]}'
