Python中读取CSV文件的方法

1.利用csv库

import csv
csv_file_object = csv.reader(open('csv/train.csv', 'rb'))       # Load in the csv file
header = csv_file_object.next()                             # Skip the fist line as it is a header

2.利用pandas

import pandas as pd
# For .read_csv, always use header=0 when you know row 0 is the header row
df = pd.read_csv('train.csv', header=0
