Hi Datalab! Thanks so much for your help!
Here is the code that previously worked:
specids = galaxies[0:3]
results_II = client.retrieve_by_specid(specid_list=specids)
results_II.info
records_I = results_II.records[0]
specid_I = records_I.specid
flux_I = records_I.flux
wavelength_I = records_I.wavelength
pd.set_option("display.max_rows", len(galaxies))
pd.set_option("display.expand_frame_repr", True)
pd.set_option('display.width', 1000)
DataFrame = pd.DataFrame([[r.specid, r.flux, r.wavelength,]
for r in results_II.records],
columns=['specid','flux', 'wavelength'])
