Python读取CSV文件

普通方法读取：

 

with open("fileName.csv") as file:
    for line in  file:
        print line

 

用CSV标准库读取：

 

import csv
csv_reader = csv.reader(open("fileName.csv"))
for row in csv_reader:
    print row

 

用pandas读取：

 

import pandas as pd
data = pd.read_csv("fileName.csv")
print data

data = pd.read_table("fileName.csv",sep=",")
print data
