In an array, list indices must be integers or slices, not str error python

I have a code which reads data from .tsv file then turns its columns into arrays. However, when i try to use those arrays in for loop it says "TypeError: list indices must be integers or slices, not str". How can i fix this?

Here's my code:

import pandas as pd
import astropy.units as u
import astropy.coordinates as coord

column_names = ["#paper", "Object", "RA","Ra2","DEC","Dec2"]
"""data = pd.read_csv ("jwebb.tsv", sep = '\t')"""


data=pd.read_csv("jwebb.tsv", sep = '\t', names=column_names)

STARS=data.Object.to_list()
RA=data.RA.to_list()
DEC=data.DEC.to_list()




for i in STARS:
    from astroquery.simbad import Simbad
    result_table = Simbad.query_object(STARS[i], wildcard=True)
    print(result_table)

A dataframe has no attribute called 'Object', 'RA', or 'DEC'. If those are columns you have to access them using:

Stars = data["Object"].to_list()
