Reading column names alone in a csv file

Question

I have a csv file with the following columns:

id,name,age,sex

Followed by a lot of values for the above columns. I am trying to read the column names alone and

Answer 1

here is the code to print only the headers or columns of the csv file.

import csv
HEADERS = next(csv.reader(open('filepath.csv')))
print (HEADERS)

Another method with pandas

import pandas as pd
HEADERS = list(pd.read_csv('filepath.csv').head(0))
print (HEADERS)

Answer 2

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.

Answer 3

import pandas as pd
data = pd.read_csv("data.csv")
cols = data.columns
