从python中的csv文件中提取列名

Question

I have a large csv file with 100's of columns in it. Currently im able to read the csv file and its particular row. My file is inside a zipfile and here is the code i have so far.

import os, sys, csv, zipfile

zip_file = zipfile.ZipFile('some_zip_file.zip')
f = zip_file.open('some_csv_file.csv', 'r')

for row in csv.reader(f):
    print row[1]

f.close()

But is there a way to extract only the column names from the csv file? Im using python 2.7

Answer 1

next(csv.reader(f))将仅返回第一行（大概在列名所在的位置。）

Answer 2

Just get the first line of the file, by your code:

import os, sys, csv, zipfile

zip_file = zipfile.ZipFile('some_zip_file.zip')
f = zip_file.open('some_csv_file.csv', 'r')

for column in csv.reader(f).next():
    print column
    # collumn_name

Hope that helps.
