#print(data)
names=data.columns

data1= pd.DataFrame(data,columns=names)
#print(data1)

  os.system('wget --auth-no-challenge --user=xxxx@gmail.com --password=xxxx -O ztf.csv "https://irsa.ipac.caltech.edu/cgi-bin/ZTF/nph_light_curves?ID={0}&FORMAT=CSV"'.format('oid'))

Why aren't you using `columnData` in the loop? – Barmar Aug 22 '21 at 20:44

Maybe `format('oid')` should be `format(columnData['oid'])`? – Barmar Aug 22 '21 at 20:45
no data1 is not empty,i checked it with the print statement – Arghya Chakraborty Aug 22 '21 at 21:03
@Barmar format(columnData['oid']) gives string indices must be integers error – Arghya Chakraborty Aug 22 '21 at 21:49

Use `for columnData in data1.itertuples():` – Barmar Aug 22 '21 at 21:53
