Answer 1

How about

with open(csv_input_path + file, 'r') as ft: header = ft.readline() # read only first line; returns string header_list = header.split(',') # returns list;

I am assuming your input file is CSV format. If using pandas, it takes more time if the file is big size because it loads the entire data as the dataset.
