As i need to read something from a csv file using python.  I got something and put it here.

Module: csv

import csv

FILE_FULL_PATH = ‘D:\\Work\\script\\My Script\\Book1.csv‘

def f():
　　with open(FILE_FULL_PATH,‘rb‘) as csvfile:
　　　　for row in csv.reader(csvfile, delimiter=‘ ‘, quotechar=‘|‘):
　　　　print type(row)
　　　　　　for eachcol in row:
　　　　　　print eachco

if __name__ == ‘__main__‘:
f()

OUTPUT:

C:\Python27\python.exe "D:/Work/script/My Script/my-test.py"
<type ‘list‘>  #here we know each row is read as a list
Col11,Col12,Col12,,COlE  #The col which is empty is stored as a empty in the list
<type ‘list‘>  
Col21,Col22,Col23,,

Process finished with exit code 0
